Abstract: A data processing center computer receives a transaction request from a mobile payment platform (MPP) computer. The transaction request is related to a purchase initiated from an account holder's mobile telephone, and includes a mobile telephone number, a merchant identifier (ID) of a merchant, and a transaction amount. The MPP computer is operated by or on behalf of a service provider having the account holder as a customer. The process also includes translating the account holder's mobile telephone number into the account holder's payment card account number, identifying a merchant acquirer computer, and generating a purchase transaction request including the account holder's payment card account number, the merchant ID, and the transaction amount. The data processing center computer then transmits the purchase transaction request to the merchant acquirer computer for authorization processing.

Abstract: A method includes receiving an information translation request, where the request is for translation of an account holder's mobile telephone number into the account holder's payment card account number. The request is related to a purchase transaction. A database is accessed to identify the account holder's service provider and a transaction acceptance request is transmitted to the service provider. The service provider provides an indication that the account holder has accepted the transaction, and the account holder's mobile telephone number is then translated into the payment card account number, which is then transmitted in response to the information translation request.
