Fuel dispensing terminal and proxy system and method of redundancy

A payment terminal for a fuel pump, the payment terminal comprising a processing unit, a memory, a secure card reader, and an encryption module, wherein the memory has computer-executable instructions stored thereon that, when executed by the processing unit, cause the payment terminal to execute a payment application for facilitating payment transactions, wherein:

• the payment terminal is configured to communicate with a payment processor such that encrypted secure payment information is transmitted directly between the payment terminal and the payment processor to complete the payment transactions comprising payment authorization by encrypting data directly using the encryption module such that the processing unit completes the payment transactions without communicating with a forecourt controller, the forecourt controller being configured to communicate with one or more point of sale systems using established protocols, and
• the payment terminal is configured to communicate with the forecourt controller through a gateway device to complete fuel dispensing, the gateway device being configured to communicate with the forecourt controller using the established protocols of the point of sale systems.
