ABSTRACT:
An electronic device with no moving parts identifies and counts coins. The device may comprise a plurality of sensors and appropriate circuitry for interpreting the signals emitted by the sensors. In a preferred embodiment, a sensor to detect the presence of a ferrous object, a sensor to detect the presence of a solid object, and a sensor to measure the weight of a coin are each implemented in an inexpensive and reliable manner by use of electronic components. Sensed information is collected and processed by a programmable microprocessor.
