How Quick Response (QR) Codes Function

Invented in 1994 by the Japanese automotive company Denso Wave, the Quick Response (QR) Code is a two-dimensional matrix symbology designed to be read optically at high speed. Unlike linear one-dimensional barcodes that encode information only horizontally, QR codes encode data across both horizontal and vertical axes, allowing them to store up to 7,089 numeric characters or 4,296 alphanumeric characters.

Static vs. Dynamic QR Codes: The Privacy & Reliability Difference
