ABSTRACT:
An auditing system for vending machines, preferably parking meters, that facilitates external exchange of digital information. The instant auditing system provides for electronic interrogation of the parking meter circuitry from portable, hand-held apparatus. The auditor is capable of processing and storing data derived from parking meters. In one form of the invention, communication is derived through the meter debit card payment slot. In an alternative embodiment data is optically exchanged and communicated between the auditor and the parking meter through infrared light. The auditor of the present invention can be interfaced with a personal computer through a standard RS232 serial port and appropriate interfacing software.
