QR Code: what is it and how does it work?
"QR Code” stands for Quick Response Code and is a code containing text. It appears in the form of a square made up of black and white squares arranged differently depending on the content.
In contrast to a barcode, a QR code does not only consist of a sequence of numbers and letters, but also of often complex sequences of information.
The convenience of the QR code lies in the fact that it can be conveniently deciphered using the camera on your smartphone and that you can immediately view and download the information it contains: documents, links, telephone contacts, etc.
