Abstract
A disclosed battery powered security monitoring system provides a security system that monitors validation signals detected by a sensor at least twice during each oscillation of the validation signal. This technique may be applied both while the main power to the gaming machine is on and while a backup power source (e.g., a battery) is on. Preferably, the security system of this invention employs a custom integrated circuit (e.g., an end-user programmed complex programmable logic device) to perform some the security functions such as supplying the validation signal to the sensor and comparing a sensor output signal to the validation signal to determine whether access to a gaming machine device has occurred.
