MasterPass enables online merchants to convert browsers into buyers by providing a fast, convenient, and secure checkout experience. The consumer uses their MasterPass wallet app to scan the QR code on your webpage, chooses the payment card and shipping details they wish to use and completes the payment. The payment information is submitted to the acquirer as usual for processing.
MasterPass is an open platform. Along with MasterCard-branded cards, the service allows consumers to pay with Visa and other branded credit, debit, and cheque cards. At this stage, American Express and Diners Club are excluded.
