Awesome Cloud Scanner

This project was specificly crafted for the Cloudflare Developer Summer Challenge.

It is a proof of concept which uses the following techniques:

  • Cloudflare Pages
  • Cloudflare Workers
  • Cloudflare Workers Durable Objects

It is a simple QR code scanner that will only allow one scan per unique code. If you scan it for the 2nd time – from anywhere in the world at any point in time – it will result in a red screen.
