A method is disclosed identifying a customer during a point-of-sale transaction. Within the method, a computer system may associate or link a first character string to a computing device possessed by a customer. Subsequently, the computer system may initiate a point-of-sale transaction with the customer at a point-of-sale system. In the transaction, the computer system may receive payment data from the customer and first location data from the computing device. From the payment data, the computer system may obtain a second character string. Accordingly, the computer system may identify a match between the first character string and the second character string and between the first location data and second location data corresponding to the point-of-sale system. Thus, the computer system may determine that the computing device is a proper recipient of an electronic receipt documenting the transaction and send the electronic receipt to the computing device. |
