In order to pay with cryptocurrency using our POS terminal, a person who accepts the payment should open previously installed application on his mobile device (available for iOS or Android), then enter the payment amount and select the cryptocurrency in which the payment is to be made. After confirmation, a QR code will be displayed, which client should scan using his external wallet. Payment is valid for 15 minutes due to the fluctuating rate of cryptocurrencies. After this time, the payment can be refreshed. Then a payment amount will be recalculated at the current exchange rate. After scanning the displayed QR code, funds will be transferred and the transaction confirmation will appear on the POS terminal. Funds will be added to BitBay Pay balance immediately after receiving required amount of confirmations from the network.
