TapCash
An offline point-of-sale and stored-value wallet for events — the balance lives on the card, and the app works with no internet connection.
Works with no signal
No server, no account, no network calls. Balances are written to the NFC cards themselves, so a venue with no connectivity is a non-issue.
Balance on the card
Each card carries its own cryptographically signed balance. Taps read and write it directly, and a tampered or stale card is refused rather than trusted.
Built for a bar shift
Operator PINs, staff and admin roles, a product grid with images, and an on-device sales log you can reconcile and export at the end of the night.
