QR Codes: Ideas to Take Advantage of Them in the Digital Home

Now that many are rediscovering the use of QR codes to consult the menu in restaurants and cafes, why not take advantage of this technology within the home. Here you have several ideas to take advantage of QR codes at home and, of course, how to read and create your own.

What are QR codes

QR Codes: Ideas in the Digital Home

QR codes are nothing new. They were invented in 1994 by the Japanese company Denso Wave, a subsidiary of Toyota, and have been used to varying degrees since then. But before we go on, what exactly is a QR code.

If for some reason you are still not clear, QR codes are a two-dimensional dot matrix or barcode capable of storing various information. For example, you can store information related to a web address, email, or simple plain text.

The QR codes support different versions depending on the number of modules that make up the matrix. That means it can go from 1 to 10, which would result in arrays of at least 21 x 21 modules up to a maximum of 177 x 177.

With multiple options when it comes to customizing them, since they even support the use of colors and gradients, to read these codes you need a QR reader . This is no longer a problem today, because since the arrival of smartphones, anyone can use their camera to do so through applications that in many cases are already installed by default, such as Google Lens or the native camera app. And still there are users who are surprised when they find out how to read one of these codes through a device they always carry in their pocket and the information they contain.

Anyway, now that you know what all this QR code is, the next step is to know how to create them . To do this, simply use one of the many online services that exist. Some proposals that you will see below allow you to generate your own code with information as varied as links to web pages, location on a map, email address, plain text, Wi-Fi password, Vcard, etc.

These services are some of the most popular you can find, but there are many more. Even applications to use locally, without the need for an internet connection. But it is still more comfortable to have to swim doing unnecessary installations.

Ideas to take advantage of QR codes at home

You already know what they are, also how to generate them, but now you need ideas. So, here are some practical uses that you could make of QR codes that could help you when carrying out certain actions at home, consulting information, etc. And yes, also be useful for those who are going to visit you.

Share the password of the wifi network for guests

Many operators began using QR codes on the stickers placed on their routers to facilitate users’ access to the default Wi-Fi network . Even so, as it is normal for you to change the name of the network and its password, with a code generated by you you will be able to facilitate this access, mainly, to your guest Wi-Fi network.

So, configure your network, access a service that allows this option and create your QR code to access your wifi network for guests. Then put that code in a visible place when entering the house or living room. In short, the most common places where your guests will be.

Important information

If you need to have important information always available and, in addition, it is extensive, it is best to resort to solutions such as those offered by QR codes. Through a link that points to a web, PDF document or plain text directly, you can have all that data always accessible.

It should not be something of life or death, but you can use it to have the phones of establishments you usually go to, health or security services, etc. These last examples can be interesting if you rent your house or receive guests on a regular basis.

Catalog the contents of boxes, cabinets and much more

The idea of using QR codes to access all the content stored in a box, closet or location is one of the most interesting. If they are places that are not easy to access, because they are in another location or because they are bulky boxes placed in uncomfortable places to access, create a QR code to catalog the content.

In this way, when you need to know what is inside or if it is what you are looking for, you will only have to read the QR code and get out of doubt. Goodbye to that of going down to the storage room to find whether or not that photo album, tool or whatever. Of course, you have to be disciplined and keep the registry updated.

Sending predefined messages

With a QR code you can also create an action through which to send a prerecorded or predefined message . It may seem unnecessary, but there will be times when it is just the opposite. Here, as always, it is a question of whether or not you can take advantage of the idea and how.

If you live with people with possible disabilities it can be interesting. Also if you rent your house and seek to facilitate your tenants contact in emergency or need situations.

Tell stories

In the same way that you can use QR codes to link to a web page , why don’t you use them to tell stories. For example, if you are printing photos, you could add a code that links to the Instagram post where you commented on that photo taken, where you told what you were doing, feeling or whatever.

This that is used so much in art galleries to expand information on the work is something that you can replicate at home for your own personal stories. That way you will never be forgotten and those who see it will know what happened at that time.

Instruction manual for your appliances

For those of “where will I have put the instruction manual” the QR codes can be a total salvation. Create laminated stickers and paste them with the QR code that links to the PDF instruction manual on the manufacturer’s page or that you have downloaded and saved on your own server or location in the cloud.

You will never have problems again, nor will anyone who needs to consult things like the operation of the washing machine, etc.

Home QR codes, more useful than they seem

As you can see, these are some ideas, mixing them with each other and combining with other technologies you can achieve many interesting things at home. It is all a matter of experimenting and rethinking ideas. But knowing how easy it is to create and read them through a device that we always carry, it is to not think about it and start using them.
