ABSTRACT:
A power failure detection system for detecting power failures in a cash dispenser machine and in an associated card reader includes an external signal input part for receiving a power failure signal from a first power failure sensing circuit located in a host cash dispenser machine, a card reader associated with the cash dispenser; an internal power source located in the card reader, a second power failure sensing circuit located in the card reader; a power failure signal output part for receiving and processing power failure signals from the external signal input part and from the second power failure sensing circuit. The power failure signal output part contains a circuit to output a final power failure signal if either the card reader or the cash dispenser has a power failure wherein the shape of said final power failure signal indicates whether the card reader or the cash dispenser or both experience a power failure.
