What Is Tap‑to‑Pay with Crypto?
Tap-to-pay with crypto transforms how we spend digital assets. Instead of converting crypto manually or using a prepaid card, users tap their phone just like Apple Pay or Google Pay. The Oobit app handles real-time crypto-to-fiat conversion at any NFC-enabled terminal.
How it works:
- Connect your Metamask wallet through Walletconnect on the Home screen
- Authorize the connection and transfer funds
- Tap your phone to pay
- The system converts crypto to fiat on the spot
- Payment completes instantly
