Abstract
A radio-frequency identification (“RFID”) system for tracking items stored in a safe. The RFID safe system may include at least a safe and an RFID system. An RFID antenna may be fixed inside the safe. For example, the RFID antenna may fixed on an inner surface of a door to the safe such that the RFID antenna sends and receives signals across multiple angles as the safe door opens and closes.
Claims10
An RFID safe system, comprising:
- a safe having at least a moveable safe door and a safe chamber with a plurality of inner walls;
- and
- an RFID system comprising an RFID antenna for emitting an RFID signal to activate at least one RFID tag, and for receiving a reflected signal from an activated RFID tag, and an RFID reader for interpreting data from the signal reflected from the activated RFID tag;
- wherein the RFID antenna is fixed to an inner surface of the safe door, such that, as the safe door opens or closes, the direction of the RFID antenna signals are swept across a geometric plane and are reflected from the inner walls of the safe, thereby increasing the probability of proper alignment of the RFID signal from the antenna with the RFID tag, and increasing the probability of detection of the RFID tag.
