You can get plastic NFC cards. I bet there are companies that will print and program them.

It must be possible to have flexible paper-like cards because my city has one-time tickets with NFC. Game would be nicer with card stock and not rigid plastic.

DropMix was an NFC DJing game that used RFID playing cards. It’s been done/could be done again.

You can program them with an app on your phone or Flipper Zero.
