What is it?
QR codes (Quick Response codes) are two-dimensional matrix barcodes invented in 1994 by Denso Wave for tracking automotive parts. They can store significantly more information than traditional barcodes—up to 4,296 characters compared to about 20 digits. QR codes use Reed-Solomon error correction, allowing them to be read even if up to 30% of the code is damaged or obscured. They're read by smartphones and dedicated scanners, which decode the pattern of black and white squares into usable data like URLs, text, or contact information.
