About MobilePay
General information on MobilePay
MobilePay is a mobile payment solution. If the customer selects this payment type in the online shop he can pay by entering his mobile phone number. A request is sent to the customer's MobilePay App and the customer confirms the purchase on his smartphone. This payment solution simplifies the payment procedure because the customer's card is stored in the app, making it unnecessary to input the card number. With its POS functions MobilePay is also prepared for payments via Bluetooth or QR-Code. The receipt of invoices and their payment is also possible.
