What is a QR Code?

A QR (Quick Response) code is a two-dimensional barcode that can store URLs, text, and other data, readable by smartphone cameras.

QR codes are matrix barcodes that can encode various types of information. When scanned with a smartphone camera, they can open websites, display text, or trigger actions.

How QR Codes Work

QR codes use a pattern of black and white squares to encode data. The pattern includes position markers, alignment patterns, and the actual data encoded in binary format.
