QR Code

A QR Code (Quick Response) code is a method of writing data in a way that can be found and read particularly quickly by machines.

This process is very robust, and therefore highly widespread, thanks to its automatic error correction functions. A QR code is a two-dimensional code developed by the Japanese company Denso Wave in 1994.
