Abstract
A coin fraud detection sensing system is provided that includes a coin chute and one or more sensing devices coupled to the coin chute. The one or more sensing devices are operative to detect a coin or other object in the coin chute and transmit a signal to a processor that determines the travel speed of the coin through the coin chute, the travel direction of the coin through the coin chute or the sequence of signals received from the sensing devices. Based upon the travel speed, direction and/or sequence, the processor is programmed to detect whether the coin is being fraudulently controlled by a withdrawal device, such as a string.
