I need your help in as per subject securing QR code but under below terms.

  • QR code will be available for scan by Hotel room guest.
  • Each room will have different QR code
  • QR code should be avalieble/accessible 24hrs only unless you scan again as a guest

Now my question here is about idea, how do I can secure it so somebody who will take picture of this QR code and try accessing it from home or elsewhere will get access denied.

This is purely advice and option search topic here, I am not asking for codes examples etc.

I was thinking about having system to generate new tokens for each room every 24hrs which is fine and durable but I am lacking to understand how I can then check this and with what?

Any ideas welcome.
