This app provides a demonstration app for performing closed-loop cashless payments with NFC using TapTrack technology using a mock internal database of menu items and categories instead of integrating with an API.

NOTE: In order to provide the most convenient demo experience, this app uses an in-memory virtual representation of an NFC tag to store user balance information. This means that tabs will not be persisted across application restarts, but you can safely use any tag in your possession to simulate the procedure as nothing will be written to it. In an actual cashless payments solution, the app can be configured to write to several different tag types ranging from basic password-protected tags to advanced cryptographically-secured tags.
