Transactions with service rail conversion

A system for processing a transaction, the system comprising:

• a network interface for receiving a request, from a wallet application, to perform a transaction to transfer funds from a payor account over a first payment rail;
• and
• a processor coupled to the network interface, the processor configured to:
• determine whether a second payment rail having a reduced processing cost relative to the first payment rail is available for processing the request based upon a determination that the second payment rail meets a requirement of the transaction;
• upon determining that the second payment rail is available:
• convert the request to a request for processing using a second payment rail different from the first payment rail;
• and
• process the request using the second payment rail.

A non-transitory computer-readable medium including instructions that, when executed on a processor, cause the processor to perform operations including:

• receiving a request, from a wallet application, to perform a transaction to transfer funds from a payor account over a first payment rail;
• determining whether a second payment rail is available for processing the request based upon a determination that the second payment rail meets a requirement of the transaction, the second payment rail having a reduced processing cost relative to the first payment rail;
• and
• upon determining that the second payment rail is available, converting the request to a request for processing using a second payment rail different from the first payment rail, and processing the request using the second payment rail.
