What goes into a QR code
A QR code stores text. Scanners interpret the text by its prefix: https://… opens a link, tel:+91… dials, mailto: starts an email, WIFI:T:WPA;S:name;P:password;; joins a network, and upi://pay?pa=name@bank&pn=Name&cu=INR opens a UPI payment. Built-in error correction (levels L, M, Q, H recovering 7% to 30% of damage) lets a code scan even when partly dirty or covered.
