QR？
QR (Quick Response) codes are two-dimensional barcodes that can store text, URLs, contact information, and other data. They were originally developed for the automotive industry but are now widely used for mobile payments, marketing, authentication, and information sharing. QR codes support error correction (L, M, Q, H levels) that allows partial damage recovery. Higher error correction levels increase reliability but reduce data capacity.
