ABSTRACT:
A coin counter attached to a vending machine and a microprocessor controlled portable collection unit (PCU) are provided for monitoring vending machine operations. This enables transactions of the machine to be calculated, stored and recorded. The coin counter forms part of a microelectronic circuit (e.g. a MOS type) and is attached or mounted as a package to the vending machine. The counter is primarily designed to count net coin intake but can be programmed to provide other information such as coin collection times, vending machine number, code validations, etc.
The PCU has a keyboard to input information to the counter and access information therefrom; the PCU calculates the coin count value and displays this value and the other information on an LED, printer, etc., upon input of a suitable access code.
The PCU may be employed for servicing a number of vending machines to better pinpoint responsibility for collection deficiencies, determining location and machine effectiveness, peak load times, and so forth. The information so obtained can be maintained secret within the PCU itself and can be accessed only upon the input of the correct code.
