A near field transaction system includes a first transaction device having near field communication circuitry, and a portable device having near field communication circuitry. The system also includes at least one transaction server having a memory area with at least one application program, and a mechanism for establishing a data link between the server and the near field communication circuitry of the portable device. The application program is configured to perform a transaction with the first transaction device, using the near field communication circuitry of the portable device as a proximity relay to communicate with the first transaction terminal.
