ABSTRACT:
A vending machine, coin-operated self-service machine, utility meter etc., is provided with a counting mechanism which is inexpensive and simple in construction and easy to operate. The device comprises a binary counting device capable of storing cumulative counts of transaction information. The binary counts are converted in a parallel to serial converter and ultimately pulsed in a series of long and short pulses to an LED. The vending machine, self-service machine, etc., is provided with a bar code serial number, and a bar code reader reads and stores both the serial number and the transaction information delivered through the LED. Software is provided to permit the storage of transaction count information based upon the serial number of a particular machine.
