QR-Code
Description
The QR code (Quick Response) is a two-dimensional code that uses wide lines, dots and gaps in between to store information that is read out using suitable hardware such as smartphones.
The high-contrast color representation is important for the creation and use of the QR code, as otherwise information can be lost during "scanning".
