I decided to build a Hide & Seek game, where one person would select a room in a virtual house to hide in, and the other person would seek them out using the NFC scanner on an Android phone. I managed to get everything working in the end, resulting in two small web apps.

One webapp is for the person hiding, where they can select where they're hiding:

The room they select is saved to a remote database, which can be read by another web app for the seeker:

They press the Scan button to enable the NFC scanner, and then move their phone over a physical paper map of the house, embedded with NFC tags. When the scanner reads a tag for a room, it will display whether the person is hiding in that room or not.

The code is available on GitHub.
