Vamos descobrir os variados aspectos da madeira através de algumas peças de mobiliário dos nossos especialistas da Homify.
Um clássico: a mesa de madeira
Haverá algo mais clássico do que uma mesa de madeira numa cozinha ou sala de jantar? Há diversos tipos de madeira que consoante os estilos são aplicados de diversas formas na criação de mesas feitas com este material. Desde o estilo rústico, até ao mais elegante, passando por itens como este, que apresenta um toque industrial. Aqui, a típica mesa de madeira maciça de quatro pernas revela um elemento de metal, uma estrutura na parte inferior para alterar o estilo da mesma.
Metal e madeira remetem para um casamento perfeito que está cada vez mais in. Dois materiais nobres que coexistem em perfeita harmonia: a madeira confere elegância ao metal, e este, por sua vez, torna a madeira mais moderna.
Além do estilo rústico
Embora muitos identifiquem a madeira com o design rústico, é possível constatar que existem muitos estilos que elegeram a madeira um dos seus respaldos. O estilo escandinavo é um deles. Como exemplo, apreciemos estas cadeiras feitas de madeira maciça com uma estrutura de ferro lacado que podemos encontrar disponível em várias cores. Tanto a madeira como o metal são tratados e pintados, sendo possível escolher desde o tom natural a uma cor clara que permite expor a madeira, passando pelo preto que cobre tudo.
A banheira de madeira
Podemos ficar surpreendidos ao encontrar uma banheira de madeira, não obstante tendermos a associar a água como um dos inimigos desta. No entanto, este material é muito comum em banheiras japonesas, usado mesmo antes do ferro fundido. As banheiras de madeira não são esteticamente deslumbrantes, mas revelam ser mais agradáveis ao toque, mais quentes. Embora não quebrem ou descolorem, requerem alguns cuidados específicos. Após cada uso, devem ser lavadas em água corrente para remover todos os vestígios de espuma, que podem vir a enfraquecer o material.
Além disso, como toda a superfície de madeira, não devem ser usados detergentes químicos para limpeza e de vez em quando é necessário aplicar óleo ou outros produtos apropriados para conservar madeira.
Desde o simples pinho até à elegante madeira de nogueira, passando pelas madeiras claras, como vidoeiro ou faia até ao extraordinário ébano, o campo é ilimitado. As caraterísticas de cada madeira vão além da cor. Existem mais resistentes como o carvalho ou teca até mais suaves e flexíveis como o abeto. Para mobiliário decorativo, como esta original e eclética cômoda, podemos misturar diferentes tipos de madeira e jogar com texturas e cores.
Dormir na floresta
Pode se constatar que os projetos em madeira vão além do estilo rústico, mas também é verdade que é num ambiente rural que a madeira pode exibir sem limitações as suas irregularidades. Esta cama parece ter saído recentemente floresta e nela podia muito bem ter dormido a Branca de Neve após ter comido a maçã envenenada. A madeira, sendo um elemento natural, tem imperfeições que a transformam num material singular.
Nesta cama podemos sentir o toque áspero do tronco e os traços da passagem do tempo.
As múltiplas utilizações desconhecidas do botox
Muito se fala de botox, mas pouco se sabe sobre ele – pelo menos os mais distraídos. Ao contrário do que vulgarmente se diz, o botox não serve para engrossar os lábios, muito pelo contrário: não é um volumizador, mas sim uma toxina que bloqueia a contração dos músculos, sendo utilizada, por exemplo, no tratamento das rugas de expressão. Mas não só.
A utilização do botox abrange diversos tratamentos, em zonas do corpo muito além do rosto, como axilas ou até mesmo os pés. O cirurgião plástico João Bastos Martins, especialista em cirurgia e medicina estética, dá a conhecer três utilizações menos conhecidas:
16% da população portuguesa sofre de enxaquecas, que é já a décima doença mais incapacitante do mundo. Na cabeça, são vários os nervos que passam através de músculos e, quando estes se contraem, os nervos são comprimidos ou demasiado estimulados, provocando enxaquecas.
A injeção de toxina botulínica em pontos chave vai paralisar temporariamente os músculos, aliviando a compressão sobre os nervos que provocam essa dor. O local onde é injetada a toxina depende do tipo de enxaqueca e da zona onde esta se desencadeia: se no músculo juntos às sobrancelhas, perto do nariz, nas têmporas, no pescoço ou noutra área. Se a dor for na zona posterior, a aplicação é feita na parte de trás da cabeça.
O efeito pode demorar dois a três dias a sentir-se, mas as melhorias são evidentes e o resultado de uma única aplicação pode durar cerca de três a seis meses
2. Sorriso gengival
O sorriso é um dos principais pontos da face - o cartão de visita - e visto como a arma mais poderosa de qualquer pessoa, capaz de mostrar a satisfação ou falta dela, de cativar ou afastar. Apesar de não existir, oficialmente, um sorriso ideal, certo é que já se definiu socialmente que um sorriso onde se veja demasiada gengiva, ou seja, em que o lábio superior sobe muito, não é o mais bonito e procura-se corrigir esta exposição demasiada sempre que possível.
O músculo elevador do lábio superior e o músculo das asas do nariz são dois dos principais responsáveis pelo sorriso e os que interessam tratar: aplicando botox nestes músculos vai descontai-los e diminuir a subida do lábio, expondo menos gengiva, o que se traduz num sorriso mais equilibrado e elegante.
Duas semanas após a sua aplicação o paciente tem um novo sorriso, que pode persistir durante quatro a seis meses.
3. Transpiração excessiva
Suar em demasia pode afetar grandemente a vida amorosa, profissional e social. Um simples aperto de mão pode ser um grande constrangimento, quer para quem sofre de hiperhidrose (sudorese em excesso) na zona das mãos como também para o seu interlocutor.
Nestas situações, em que esteja diagnosticada a hiperhidrose, o corpo exige uma solução externa, pois os mecanismos de controlo interno estão desregulados. O botox traz a possibilidade de amenizar os níveis de sudorese de uma forma simples e pouco intrusiva, tanto nas axilas como em mãos e pés: o suor sai pela contração do músculo nas glândulas que o produzem e a toxina vai paralisar essas glândulas, fazendo com que deixem de produzir suor.
É aplicado em vários pontos das zonas afetadas, com um espaçamento de cerca de um centímetro entre cada picada. O tratamento é superficial, não afetando o normal funcionamento do corpo, e deve aplica-se de seis em seis meses para resultados duradouros.
Os tratamentos com a toxina botulínica devem ser pensados caso a caso, conforme a real necessidade do paciente e o seu estado de saúde. Existem diferentes tipo de botox, com diversas formulações e para variados fins, sendo essencial uma utilização totalmente personalizada. O número de aplicações e os seus resultados vão sempre depender da anatomia e características musculares do paciente, podendo ser necessárias várias aplicações.

Scan.me solves the QR code dilemma by delivering a simple, beautiful experience
It would be easy to say that QR codes kind of suck and leave it at that. People have been talking about these square symbols with embedded information like URLs for years, claiming that they’re the future of advertising and information distribution. But they never seem to live up to their promise.
Now, Scan.me feels it has the QR code problem solved and, after seeing what the company is up to with the latest release of its app for iOS and Android and the enhancements to its web service, we’re inclined to agree. By building a great experience on both sides of the equation, with a ‘gold standard’ scanning app and a simple, beautiful landing page for every QR code generated, the company is looking to craft a benchmark code scanning system.
Make invaluable connections
Scan.me isn’t coming into this fresh to the code scanning business. It’s current app has over 10 million downloads and its used the data from their experience with this as well as with partners on the other end of the equation, businesses and content providers, to work improving its service. Its also received $1.7M in funding from a host of partners including Google Ventures.
Now, the scanning app has hit version 1.9 with a slick new interface and the web interface for creating codes to scan has gotten a major overhaul as well. The app now also scans regular barcodes as well with plans to add more formats, with a zap of a barcode taking a user to an Amazon, Google or direct product page.
The app is designed to be fast and focused, allowing a user to scan a code and get results, without much more fluff. But, as the Scan.me guys have figured out, this is only part of the experience, and not even the most important bit.
You’ve probably seen QR codes around, on packaging, in magazines, on a placard at a department store advertising discounts or an email catalog. But they’re typically poorly displayed and designed, making for a lame first impression.
Scan.me’s codes are presented with a ‘call to action’ like ‘Scan this to Like us on Facebook!’. They’re designed beautifully, with a standard URL for non-scanners and a crisp look that presents well. Businesses or individuals can build one of these codes with the QR code generator on the Scan.me site, which has templates for profiles, social networking actions and websites.
But getting someone to scan a code isn’t the hard part either. It’s getting the user to a virtual location that looks and feels inviting and enabling a business to start a conversation with them.
“We think that having social actions on the scan pages invites conversation between the person and the business,” says Scan.me’s Garret Gee, talking to me about the new site and app. The biggest issue, it turns out, isn’t getting a user to scan a code, it’s getting them to do something after that.
Typically codes will drop a user onto a page that hasn’t been optimized for mobile, or isn’t specifically designed for that purpose. This is where the company’s beautiful mobile-centric scan pages come in. They’re gorgeous splash pages that can be designed right along with the QR code on the Scan.me site. They offer simple calls to action like following the company on Twitter, Liking them on Facebook or asking them a question by email.
The pages can also, of course, be a mobile website designed by the business or person building the code. But if you don’t have the resources, Scan.me’s pages provide a great alternative.
And the process works, too. Gee told me that they recently partnered with music video site Vevo to add a code to the end of a video by electronic artist Kaskade. They convinced Vevo to try out one of their templates as a landing page and ended up with a 40-50% conversion rate on users taking action. To give you a comparison, the industry standard rate is somewhere around 1%.
COVID app triggers overdue debate on privacy in Singapore
Government forced to amend law around app after it emerges police used the data to investigate a number of crimes.
Singapore – For a country that prides itself on being on the cutting edge of high-tech governance, there has been little national discussion in Singapore on the balance between data collection and individual privacy.
Now, COVID-19 has forced the conversation, after it was revealed that data from the government’s contact-tracing app, contrary to initial promises, could also be used for criminal investigations.
The public backlash prompted the government to not only acknowledge that it had made a mistake but also to introduce new legislation to restrict the use of the data.
Under the new amendments to the COVID-19 (Temporary Measures) Act, passed in the Singapore Parliament this month, personal data collected by digital pandemic contact-tracing programmes can only be used to contact trace, unless it is required by law enforcement for investigations into “serious offences”.
Pritam Singh, the leader of the opposition, has called for an “immediate conversation” on the balance between individual privacy and the use of technology and data collection in Singapore.
“To counter scepticism and its resultant behaviours and to replace it with trust and cooperation, Singaporeans also need to better understand the necessity and ambit of data collection. This is especially so for a new generation who are more likely to be concerned about privacy and individual rights,” he said in Parliament.
Prepared by the country’s experience with SARS in 2003, the Singapore government quickly rolled out a test-and-trace strategy in the early days of the coronavirus’ emergence and poured resources into developing digital solutions to speed up the process.
Throughout the pandemic, Singaporeans have been introduced to contact-tracing programmes such as SafeEntry, which uses QR codes to register people’s entry into and exit from public venues, and TraceTogether, a Bluetooth-enabled app that swaps anonymous pings with other devices to generate a list of close contacts.
The response to TraceTogether was lukewarm when it first launched in March 2020, but adoption shot up later in the year, after the government indicated its intention to make it mandatory. Apart from the smartphone app, wearable devices – operating on the same principles – were also made available. More than 80 percent of the city-state’s 5.7 million residents has adopted either the TraceTogether app or the device so far.
To assuage concerns over privacy, the government had assured Singaporeans that digital contact-tracing data would only be used to track people down who might have been exposed to the virus. “TraceTogether app, TraceTogether running on a device and the data generated, is purely for contact-tracing. Period,” Vivian Balakrishnan, the minister in charge of Singapore’s Smart Nation initiative said at a press conference on 8 June last year. Teo Chee Hean, the coordinating minister for national security, made a similar assertion in Parliament just days before.
Half a year later, Balakrishnan was forced to admit in Parliament that he had not been thinking of the Criminal Procedure Code – which gives law enforcement expansive powers to obtain information for their investigations – when he spoke at that press conference.
“Perhaps I was so enamoured by what I thought was the ingenuity and brilliance of this that I got blindsided,” he said in Parliament last week. “I regret the consternation and anxiety caused.”
However, the Ministry of Home Affairs confirmed last week that the police had requested, and obtained, TraceTogether data for a murder investigation in May 2020 – about a month before Balakrishnan spoke at the press conference. The minister has said that he did not know of the case until October, when he was first made aware of the oversight following questions from a member of the public.
In deploying their own contact-tracing technology, other countries have also had to contend with questions about privacy and data security. Australia, for instance, developed the COVIDSafe app based on the same application protocol behind TraceTogether but passed legislation to ensure that the gathered data could only be used in contact-tracing efforts.
The government hopes that the new legislation will remedy any erosion of public trust in Singapore’s contact-tracing programmes. The new law limits police access to such data to investigations into seven classes of offences, such as rape, kidnapping, murder, or drug offences punishable by death.
Arguing that Singapore is in “exceptional circumstances”, Balakrishnan emphasised the urgent need to focus on dealing with the pandemic.
“This is crucial because the virus is a clear, present and growing threat. And it will remain so for some time. We cannot afford to be distracted from our fight against COVID-19,” he said.
“I think by and large the public still trust the government, but ‘trust’ is a rather broad word to use here,” Howard Lee, a PhD candidate researching media governance at Murdoch University, told Al Jazeera English.
“Rather, I think the public is convinced by the need for TraceTogether and are willing to give the government the benefit of the doubt, if it means using TraceTogether keeps the economy going. My belief is that the government is attempting to expand on the boundaries of that willingness by sanctioning such data breaches through legalising it, rather than address the privacy issues directly.”
But questions have arisen regarding the trade-off made by allowing law enforcement access to such information.
“While we know that TraceTogether data is critical for contact-tracing, we need to ask whether TraceTogether data is vital for solving these seven categories of crimes,” Leader of the Opposition Singh said in Parliament, referring to the classes of offences for which the authorities will still be allowed to access contact-tracing data.
Pointing to the “abundance” of other tools that law enforcement can use during their investigations – from CCTV footage, forensic examinations of devices like mobile phones and laptops, to interviews with witnesses and the collection of other physical evidence – Singh said that there was “a legitimate view that these tools should be more than sufficient in detecting crime and securing convictions.”
“There is little or no doubt that TraceTogether would make things more convenient for the police but it is my view that convenience for the police may not be a good enough reason to compromise the trust necessary to win the COVID-19 fight,” he added.
Terry Xu, the editor of local news website The Online Citizen, told Al Jazeera English that he shares Singh’s scepticism: “Hearing what has been said in Parliament, I am somewhat assured that the government will restrict the use of data to serious offences stipulated in the urgent bill. But … I doubt there is any crucial data that the [law] enforcement agencies can retrieve from [TraceTogether] for the said serious offences than what they [can already access] through the existing surveillance devices that they have access to.”
Political scientist Ian Chong told Al Jazeera English that, with this new legislation in place, “some people may be willing to give state authorities the benefit of the doubt”, but added that “others may worry that there remains few channels for recourse and remedies should there be discovery of some overreach by authority in future.”
Xu is wary of the surveillance potential of these contact-tracing systems. “There is nothing stopping the government from abusing the information to keep tabs on individuals,” he said, pointing to the hostility that the authorities might have towards the more critical members of Singapore’s civil society.
Jolovan Wham, a social worker currently facing multiple charges for participating in assemblies declared illegal by the authorities, has had mobile phones seized by the police in the course of various investigations. He told Al Jazeera English that the amount of data collection and surveillance in Singapore can sometimes feel overwhelming and exhausting to guard against.
“Surveillance is so normalised that sometimes I just want to go: ‘Fk it, I don’t care any more’,” he said. Yet he also acknowledges that he takes steps to protect his privacy as much as he can, such as using Faraday pouches that can block radio signals and prevent unwanted attacks on electronic devices.
Lee pointed out that, for a national conversation on privacy to be truly meaningful, it would be necessary for the government to first be transparent with Singaporeans about the sort of citizen data that has already been collected and how it is used.
He also said that political will to make real changes will also be necessary: “A national conversation on privacy is useless unless it also comes with an unconditional review of all laws that can infringe on our privacy, with the need to safeguard privacy made a priority rather than play second fiddle to ‘national security’ or ‘crime deterrence’.”

QR codes, aka quick response codes, can contain a lot more information than UPC barcodes. They can also be placed on items where a bar code is not practical. Emarketer says that nearly 20 percent of U.S. smartphone users have scanned a QR code. Companies are learning how to make creative use of these codes, from cemetery plots to dog walking businesses. You’ll have to look beyond a printed page to find the following unique QR code uses.
Scan That Pet
Pet Check Technology offers high-tech solutions to pet grooming and boarding companies. One of the tools they use are QR code stickers they place on surfaces as they walk the dogs. The staff scan the codes as they make their way around the route, and the path is recorded automatically. Owners can then can log into the system to see how well their animal is being taken care of.
You Can Take It With You
Well, sort of. Interactive cemeteries are showing up across the country, thanks to technology from Digital Legacys. This company creates a QR code placard that can be attached to a memorial stone that, when scanned, will take the viewer to a memorial website. The site can contain various types of information chosen by the family. Such information as family history, career accomplishments and testimonials can be stored on the site. Information such as where to send donations, or the preferred FTD funeral flowers, is something viewers would find helpful.
An article in The Pueblo Chieftain reports on an individual who, knowing his time was coming up, specified what information he wanted people to be able to access. Digital Legacys allows people to create their own information legacy highlighting the things they are most proud to share with visitors at their memorial sites.
Retailers Get Creative
Manufacturers and retailers use QR codes to get the word out about products and services. They’re beginning to use them to create brand loyalty by educating consumers about interesting aspects of their businesses.
Macy’s is now printing QR codes on signs near specific clothing brands. Scanning the codes will take the consumer to a site to learn fashion tips directly from the designer. They make suggestions as to how to wear the clothes and with what to accessorize them.
An Ethiopian restaurant called Mesob, located in New Jersey, has QR codes placed on each table. The diners scan the codes to learn about how their coffee and traditional bread is made.
During a promotion, Taco Bell and Mountain Dew printed QR codes on paper drink cups. Consumers could scan the codes and download free music.
Guinness went one better. They printed a QR code on a glass beer mug in such a way your couldn’t see the code unless the glass was full of dark Guinness. Once scanned, consumers learned about the beer-making process and the Guinness company itself.
A Montreal-based bakery, Clever Cupcakes, makes cupcakes topped with edible, and scannable, QR codes. Companies can define whatever they want to place in the codes. A gift of cupcakes to a client can contain an entire PR campaign they can view while enjoying a cupcake and coffee break.
The only question really remaining is, how can you use QR Codes for your unique business?

Perguntas frequentes sobre o serviço nos restaurantes em tempo de pandemia. O que mudou?
O “novo normal” nos restaurantes marca a fase atual de desconfinamento. Entre as novas regras, há normas que não mudam: o serviço de qualidade continuará a ser um dos ingredientes de sucesso no setor da restauração! Veja algumas perguntas frequentes sobre o serviço em tempo de pandemia, de acordo com o Guia de Boas Práticas da AHRESP e as medidas implementadas pela Direção-Geral da Saúde.
Posso disponibilizar ementas plastificadas ou em alternativa recorrer a um quadro de ardósia, um placard ou um LCD com a ementa visível a todos os clientes? Qual é a prática mais recomendada?
As ementas plastificadas devem ser desinfetadas após cada utilização. Os menus devem ser de uso único e descartáveis ou, em alternativa, pode recorrer a um quadro de ardósia, um placard, um LCD ou equivalente, onde a ementa é afixada diariamente e está visível a todos os clientes. A tendência passa por disponibilizar ementas online, acessíveis pelo telemóvel através de um QR Code [Ex.: “Menu Autêntico” da Super Bock].
As toalhas ou individuais de mesa devem ser de papel/descartáveis ou também podem ser de tecido, PVC ou outro material?
Podem ser de papel ou em tecido, mas sempre de utilização única por cliente. Podem igualmente ser em PVC ou outro material, desde que sejam desinfetadas entre cada cliente.
Se não são permitidos elementos decorativos nas mesas, qual a solução para os dispensadores de guardanapos?
Os guardanapos só devem ser colocados na mesa na presença do cliente juntamente com os pratos, copos e talheres. Os pratos, copos, talheres e guardanapos, depois de lavados, devem ser guardados em local fechado devidamente protegido e de acesso exclusivo aos colaboradores.
Ainda sobre os “motivos decorativos das mesas”, podemos manter vasos de plantas naturais ou estão incluídos nos elementos que devemos retirar?
Também devemos retirar das mesas os vasos de plantas naturais.
Os galheteiros podem ir à mesa com higienização após cada uso ou têm mesmo de ser os individuais descartáveis?
A Orientação 023/2020 não faz qualquer referência em relação aos galheteiros. Quando utilizados, devem ser colocados na mesa após solicitação por parte do cliente e higienizados a cada utilização.
O serviço deve ser realizado com empratamento individual?
Sim, de preferência. Quando não for possível, sugere-se a colocação de um talher de servir por cada cliente.
Como deve ser feito o transporte da loiça suja desde a mesa à copa?
O ideal é a existência de passa-pratos independentes com comunicação direta para a respetiva copa. Segundo as boas práticas de higiene e segurança alimentar já existentes, a cozinha deve ser próxima das copas, devendo ambas ser instaladas de forma a permitir uma comunicação rápida com a sala de refeições, sempre que possível, com trajetos diferenciados para sujos e limpos.
O que fazer quando o pagamento é efetuado em dinheiro?
Colaborador e cliente devem lavar imediatamente as mãos com água e sabão ou solução antisséptica de base alcoólica (SABA), sempre antes e depois dos pagamentos.

That's awesome! I'd like to know more about the NFC part. deets?
If you have an android phone you can simply put wifi details on NFC tags if they are writable. It used to be a feature that was just accessible via the WiFi settings if you have NFC enabled. If you don't have that setting anymore, apps like "NFC Tools" are working as well. I just made a "filament change" to insert my NFC Tag (in my case a credit card sized tag) and it worked like a charm
I can't wait till I have money to do things like this!
But a 3D printer, time, learning python, soldering shit. I want it to look nice.
You will need a printer and time, but the rest is unnecessary to make this :)
Or the wifi password is actually "justscantheqrcode" and the print just links to rickroll.
Brilliant! I'm going to need this for all the guests I will invite to visit my house!. Oh. Wait.
More detailed instructions: You can do this at qifi, or follow this procedure if you don't trust the security:
Don't trust your browser either? Just pipe the string WIFI:S: ;T: ;P:
;; through the QR code generator of your choice after reading the documentation.
To avoid repeating yourself you should write down "Scan to connect to WiFi"
Grabs phone. Types scantoconnecttowifi”. That doesn’t seem to be it.
Wanted to do the same thing how did you get the QR code?
Newer android lets you share the connected wifi details. It's under Settings > Wifi, you'll see a "tap to share password" button which creates a qr code that lets a device connect to wifi without entering the password
Some router/AP will provide the code after you setup Wifi.
AVM FritzBox (and their rebranded models) will provide the QR code; requires Fritz!OS version 7 (maybe 6 too, not sure)
You're getting downvoted, but it's like the first link in Google.
Very cool idea but I feel like explaining how to use the QR code would take 10x longer than just telling your guest the password lol. Especially since it’s information that I can express once to a group of people instead of having everyone wander over to the placard and wait in line to take a picture. Nice execution though
It's much faster than that. You just open camera, point at QR code, press the link that pops up and boom connect to WiFi. And you keep the password a secret, ish.
The password is actually in plain text shown, so its not secret (unless you use the NFC). But I think its neat and most of my friends are computer science guys, so they all know how a QR code works
I was going to say, most likely if you know how to do everything involved in making this. At least a significant amount of your friends probably are knowledgeable enough in these sorts of things to know how to use it.
Very cool idea but I feel like explaining how to use the QR code would take 10x longer than just telling your guest the password lol.
Depends on the password thought, and it's a pain to type something like:
If they really don't know how to use a QR code then just tell them the password. Big whoop.
Also you don't need to wait in line. What are you talking about? More than one person can take a picture at once.
What kind of life do you live where you have lines of people trying to get on your home WiFi?
Cellular has gotten good enough that I haven't asked for WiFi at peoples houses in years. I also don't recall a single adult guest asking for my WiFi at home. Kids frequently ask for it for their tablets.
What program/app or websites did you use to make the QR code and program the NFC tag
I love the attention to detail with the WiFi and NFC logos.
This should have a hinged lid, which says something like "open for WiFi Password", so that you, or someone else, doesn't end up accidentally posting your password to the world on Facebook, Instagram, YouTube, etc. Complete with your location, in many cases. Or a neighbor with binoculars/telescope. Should also have the network name and a cleartext version of the password for those who don't do barcodes.
A printed piece of paper, with a folded cover flap, actually makes more sense since passwords should be changed occasionally (although it is hard when you have to change it in dozens of devices, many of which aren't set up to read barcodes). You can put a (rewritable) NFC tag underneath paper, too. Make the portion that folds over have a random barcode like pattern on the back to make it harder to read through the cover with image processing. It doesn't make sense to use a piece of plastic that lasts several hundred years to hold a password that shouldn't last more than one; PLA mostly only biodegrades when you don't want it to. This would actually be more suitable for QR codes with more enduring value, like the website for your business. If you really want to 3D print it, leave the barcode out and just have a place to insert a piece of paper under the hinged lid. It also makes it easier to insert a QR code that says "thisisnotmyrealwifipassword" when posting here.
There are a few potential exceptions: a really high traffic location (such as McDonald's). A time (such as now) or place where you want to avoid physical touch. Where it makes sense for people to be able to scan it from across the room (again, high traffic location).
Never post a picture of any portion of your password. Security is often a lot less secure than you think it is and even a small amount of leaked information can compromise it considerably.
You left half of your barcode exposed. Since QR codes have a lot of redundancy involved, you may have actually exposed more than half of your password, though fortunately this may be partially made up for by the fact that the locating marks take up a good portion of the exposed area. So lets assume you lost half. But understand that exposing half your password would make it go, for example, from a million guesses to merely a thousand. So "half" is misleading as you have actually lost like 99.9% of the security. If your password was a truly random 32 character password, you have lost 99.999999999999999999999999999% of the security you thought you had. And "random" passwords often aren't very random. I once cracked every single randomly assigned password for every account on my ISP in under an hour. And the default "random" passwords on routers are not very random.
And your password is probably way less secure that you thought it was to start with.
Half of this 53 character password is missing. It should take you exactly one guess. NowIsTheTimeFOfTheirCountry
The fact that it is a well known phrase aside, if you had a 16 word password, you might assume there are something like 100000 ^ 16 combinations. Yet a mere 100 words, and slight variations of them like plurals, account for 50% of word usage in english. Of the 16 words used in that password, 12 are in the top 100 (top 76, actually), and not even variant forms, and the other 4 aren't far behind with the least frequent one being 206th most common and an average word frequency of 54th though it actually works out to 20th on average since we are multiplying instead of adding. As in, it works out to 20^16 instead of 100000^16. Which is still not shabby. Until you give half of the bits away and it ends up a mere 4 hours on machine set up with 6 GPUs for password cracking.
