A system and method to deter the theft of paper currency comprising a currency pack assembly containing coded electronics and an ignitable chemical pack. There is a coded teller sentry unit located near the cash drawer in which the currency pack assembly is stored. The currency pack assembly contains a coded transmitting/receiving apparatus that signals the coded teller sentry unit when the currency pack assembly is removed from the cash drawer. The coded teller sentry unit is connectable to a silent alarm and may trigger the silent alarm upon removal of the currency pack from the cash drawer. The coded teller sentry unit is also connectable to surveillance equipment such as cameras, and activates such equipment automatically upon removal of the currency pack assembly from the cash drawer. There is also a coded door control unit located near the egress to the building which detects when the currency pack assembly has left the building. The coded door control unit is connectable to an alarm which is sounded upon removal of the currency pack assembly from the building, and is connectable to a door locking mechanism which locks the doors of the building after the currency pack assembly has left the building. Once the currency pack assembly has left the building, a microprocessor in the currency pack assembly begins timing down to a pre-set ignition time to ignite the chemical pack. The chemical pack contains chemical dye, colored smoke, and, where permitted by law, teargas. The system can provide notification to law enforcement personnel or other monitoring systems, prevent re-entry of the thief into the building, and ideally induce the thief to abandon the stolen currency.
