What is a QR Code?
QR codes are machine-readable matrix barcodes that encode data in a grid of black and white squares. They were invented in 1994 by Denso Wave for tracking automotive parts and have since become ubiquitous for sharing links, contact information, payment details, and more. Unlike traditional barcodes, QR codes can store data both horizontally and vertically, allowing them to hold significantly more information.
