Abstract

A slot machine or any other coin-operated machine may be adapted to use a microprocessor. The microprocess is intended to check the authenticity of the coins inserted. The data obtained from the coin sensors are fed to the monitoring microprocessor and evaluated. The evaluation process involves either the measurement of frequency phase, voltage or current or a combination of these test criteria. There are also several facilities for compensating for fluctuations in the mains voltage or temp.
