MONEY TRANSFER SYSTEM GATEWAY SERVICE.

摘要

A method includes receiving, in a computer, a transaction request from a payment services provider. An end user identifier included in the request is mapped into a payment card system account number. The end user identifier identifies an end user who has been assigned the payment card system account, and who is a subscriber to a closed-loop payment system operated by the payment services provider. Funds from the payment services provider are credited to a shadow open-loop system payment card account identified by the payment card system account number. An authorization request for an open-loop system transaction is sent to an acquirer financial institution that represents a merchant with which the end user is dealing, and is received back from a payment card system authorization system by the same computer that received the transaction request from the payment services provider and that generated the authorization request.
