Abstract

There is disclosed an animal identification and entry control system based on a radio frequency identification (RFID) system including an animal collar-mounted RFID tag, and RFID circuitry including a single antenna housed within a bezel placed forward of and surrounding the entry aperture to optimize signal reception. The bezel shape allows only one animal to enter at a time. To conserve power, the circuitry is only activated when an animal pushes against a door within the device, triggering a switch mechanism. A circuit-controlled latch prevents animals from opening the door unless a code match is detected between the programmed code in the tag and a stored code in the circuit controlling the system. Multiple codes may be stored for identifying multiple animals wearing collars tagged with unique identifying codes. The system'"'"'s applications include but are not limited to controlling animal entry to feeding enclosures, human housing and animal housing.
