Hi there! I'm Weiyuan.

I initially did this for a family member, and decided to create a more "scalable" way to solve this problem for myself since I do face it often.

Another objective was that I didn't want to be tracked by a third party.

This is entirely a frontend solution. Do monitor your network console, where the QR generation process should only load the DataURL as image, and not to a backend server.

No cookies/sessions are used too.

The code can always be found here, hosted on Github Pages on the "gh-pages" branch.
