Abstract
A coin counter security circuit for use in vending machines having a counter for counting the number of vending transactions. The circuit functions to detect indicia of proper counter operation (and hence that the counter has not been improperly disconnected) and serves to enable the vend transaction when proper counter operation has been so detected. The indicia of proper counter operation can be the detection of a flyback signal normally generated by an inductive element associated with the counter.
