What is a QR Code? complete guide, history & future
Everything you need to know about 2D matrix barcodes: from their 1994 invention at Denso Wave to Reed-Solomon error correction and modern dynamic routing.
Traditional barcodes hold only 20 alphanumeric characters
Old 1D barcodes can only hold a basic serial number, cannot be read at angles, and become useless if even slightly scratched or torn.
2D matrix capacity with self-healing error correction
QR codes can store up to 7,089 numbers or 4,296 letters and can be successfully scanned even when up to 30% of the surface is damaged or covered by a logo.
