parameters related to the diameter of the
coin.

Acceptance gate
When the validator validates a coin, the
electromagnet opens the gate to let the
coin through the accepted coin channel.
12. String detector
Inside the sensor module is the “string detector system.” An electro-mechanical system to foil
any attempt at fraud using a string tied to the coin. The system is based on an infrared beam
passing through a hole in the shutter. The beam is interrupted when the string attached to the
coin tenses and moves the shutter. The validator interprets this signal as a fraud attempt and
inhibits the coin.
