2.1 Payment

1. The merchant initiates a payment request on the POS Terminal, and the user confirms the payment amount on the screen.
2. After verifying the amount is correct, place the payment card near the NFC induction area and hold it steady for 1-2 seconds without moving it.
3. A beep indicates successful card reading, and the screen displays「Card signed. You may remove your card now」. At this point, the card can be removed.
4. Once the transaction is completed and confirmed on the blockchain (typically 1-5 seconds), the screen displays「Payment Received」and shows the transaction hash.
5. The POS Terminal automatically prints a receipt.

6. After payment is completed, the balance change can be viewed in the App.

   

Note:

*If the blockchain network is congested or network quality is poor, transaction confirmation may take longer; please wait patiently.

*The current version of the App does not support transaction record inquiry. To check transaction records, please copy the USDC Deposit Address and query it on a blockchain explorer.
