QR means Quick Response — a two-dimensional barcode invented in 1994 by Denso-Wave, a Toyota subsidiary in Japan. Unlike one-dimensional barcodes, QR codes can:
Store much more data
Be scanned from any angle
Work faster and more reliably
Original purpose: Track automotive parts.
Today’s use: Global standard for payments, marketing, authentication, and information sharing.

Payments – UPI (India), PayNow (Singapore), EMVCo cross-border systems
