Abstract
A totalizer system having a first electronic device coupled to the vending machine for storing the number of vends (data) made by the vending machine, and a second device for interrogating the first device and providing a readout of said vends, e.g., in code, actual money value, or actual number of vends, or any form desired. The present system preferably includes an optical interrogation scheme using modulated light for transmitting stored vends in the first device to the second device thus eliminating human error, and an electronic memory in the first device that will store vends for a prolonged period of time even if the vending machine is unplugged.
