What is a barcode?
The QR code is a two-dimensional matrix code that stores text, links, WiFi credentials or payment data (SEPA/GiroCode) and is read by any smartphone camera in seconds.
With four selectable error-correction levels a QR code stays readable even when partly covered or damaged – ideal for packaging, posters, menus and displays.
