Abstract: The present invention is an apparatus that is contained inside the confined space of a Point of Sale Cash Register, Cash Drawer and is designed specifically to sterilize currency and or additional items placed inside the drawer, automatically. The invention includes UVC lighting source(s), either CCFL tube (spanning the length of the enclosure, and located centrally above the denomination separation slots, or by high powered LED-UVC with printed circuit board and located directly above the tray/till slots). The upper, interior surface of the enclosure is lined with highly reflective material. Each slot in the cash tray/till is also lined with highly reflective material. The system is controlled electronically, via an external power supply, that is connected to a dedicated circuit board, which is located in the rear of the enclosure, and is activated by a photo sensor each time the drawer is opened. A programmable timer initializes at the moment the drawer is fully closed.
