QR Code

A QR code is a two-dimensional symbol that holds far more data than a barcode and scans with any phone camera. The important difference from many free services: these QR codes are static and never expire. They point straight at your link, with no middleman that can track scans or switch the code off later.

  • Never expires and needs no third-party redirect
  • Built-in error correction survives minor damage
  • Great for menus, packaging, posters and business cards
