On: Mechanical sympathy for QR codes: making NSW check...

The craziest part is, the QR codes have all the data to be able to work offline. But the app requires an internet connection!

A synchronous online connection. The app stutters and generally hangs/freezes if you have poor connection, which is precisely what happens in most shopping centres.

Uh, huh, I clearly didn’t test it properly. I had thought I’d validated checking in while offline. Oops: https://github.com/huonw/huonw.github.io/commit/fd19b9d66af7...

Thanks!

Why is that crazy? The point is tracking movements, how would that be possible if the government can’t see your location?

They don't need to know where you are, they just need to know when you checked in/out along with a business identifier. Syncing the data later when you're back online would do this fine.

I checked my history the other day and noticed some businesses missing so there probably are some bugs in the process.
