QR Code: what is it and how does it work?

"QR Code" identifies a two-dimensional code that contains data. It appears as a square made of light and dark modules arranged according to its content.

Unlike a linear barcode, a QR Code can encode not only numbers and letters but also URLs, Wi-Fi configurations and contacts.

The code can be read with a smartphone camera to open or save its information. Preserve a suitable quiet zone and always test scanning before printing.
