Although they may seem simple, QR codes, which mean “quick answers” in English, are capable of storing a large amount of data. But whatever its quantity, once scanned, the QR code must allow the user instant access to this information; hence its codename rapid response. The data stored in a QR code can include (but is not limited to) website URLs, phone numbers, or up to 4,000 characters of text.
Each QR code is made up of squares and black dots that represent different information. Once scanned, the barcode’s unique pattern results in readable data. This transaction usually happens in seconds.

What is the QR code on the back of the router?
The Wifi password is a code made up of letters and numbers that only gives Internet access to a few people or users connected through a router.
In general, this secret code is somewhat complex to remember due to the characters that make it up, so many users tend to copy it. To facilitate this, routers have a QR code on the back of the device with which you can automatically access your home Internet network. You will only have to scan this code with your mobile and you will be able to connect systematically to the secure Wi-Fi. This trick works if you are not too far from the router and you scan the code with your mobile reader.
