Claims28
A retrofit audit system comprising:
- a master module containing a microprocessor capable of reading information directly from a target vending machine control system or operational device, the master module including at least one communication port;
- a plurality of sub-modules connected to the at least one communication port of the master module, the sub-modules capable of detecting additional information from the target vending machine or operational device.
An audit system comprising:
- an audit monitor controller containing a microprocessor and a plurality of input interface components operable to read information from at least one of a vending
- machine control system and an operational device, and including a plurality of output components;
- and
- at least one motor sub-module coupled to the audit monitor controller for monitoring vending machine motors.
