What Is a QR Code — And How Does It Work?
A QR code (Quick Response code) is a two-dimensional barcode that stores information — usually a website link — in a square grid of black and white dots. Your phone's camera reads the pattern instantly and opens the link without typing anything.
QR codes were invented in 1994 by Denso Wave in Japan for tracking automotive parts. Today they are scanned over 2 billion times per day globally — on restaurant menus, payment screens, product packaging, event tickets, and boarding passes.

Do QR codes generated here expire?▼
No. These are static QR codes — the information is embedded directly into the pattern. As long as your destination URL works, the QR code works forever. No subscription or account needed.
