When customers use mobile payments, the following reasons might cause a failure:
1. Circumtec's Pi and 2-in-1 black box currently do not support EFTPOS payments. Please ask the customer to open their mobile wallet, tap on the payment card, and check if EFTPOS is selected as the payment method. If so, please choose VISA or MASTERCARD instead.
2. The card reader may take some time to read the card information on the mobile device. When the mobile phone is close to the card reader and you hear a beep, please wait patiently for an extra second to allow the card reader to fully read the card information before moving the phone away.
