How QR Codes Work

QR (Quick Response) codes encode data into a 2D matrix of black and white modules. They include error correction (Reed-Solomon), allowing up to 30% of the code to be damaged and still readable.

Smartphones detect QR codes using their camera and automatically handle the encoded data type — opening URLs, composing emails, connecting to Wi-Fi, or dialing phone numbers.

Common Use Cases

  • Share website links on business cards or posters.
  • Guest Wi-Fi access — scan to connect instantly.
  • Quick contact sharing via vCard QR codes.
  • Event tickets, boarding passes, and check-ins.
  • Restaurant menus and product packaging.
  • Payment links (UPI, PayPal, etc.).
