Abstract: A currency removal sensor system for detecting removal of currency from a cash drawer includes a tray base positioned within the bottom of the cash drawer and a removable tray sitting on top of the base. A sensor is mounted at a predetermined location in the tray base and is coupled to alarm circuitry. The tray includes a number of currency compartments, at least one of the currency compartments including a pivoting currency clip having an upward position and a downward position. The currency clip includes a magnet which is suspended away from the sensor in the base when the clip is in the upward position and which lies proximate the sensor when the clip is in the downward position to activate the sensor and initiate an alarm.
