Patent ID: 11488137

Abstract:
A computerized method (200) of performing a purchase and an associated communication system are disclosed. A customer mobile computing device (CMCD) communicates (210) with a server computing device (SCD) to generate an order for the purchase. The server computing device (SCD) communicates (220) with a payment processor computing device (PPCD) to perform a first part of a payment transaction for the purchase, wherein the first part of the payment transaction involves reserving funds for the purchase. A merchant computing device (MCD) performs (230) a digital handshake procedure with the customer mobile computing device (CMCD). The digital handshake procedure involves short-range wireless data communication to verify spatial proximity between the customer mobile computing device (CMCD) and the merchant computing device (MCD). When spatial proximity has been verified, the merchant computing device (MCD) communicates (240) with the server computing device (SCD) to accept the order. The server computing device (SCD) communicates (250) with the payment processor computing device (PPCD) to perform a second part of the payment transaction, wherein the second part of the payment transaction involves capturing funds for the purchase.
