A system for providing selective access to a food cavity including a base defining the food cavity. A cover is connected to the base and moveable between a closed condition wherein the cover prevents access to the food cavity and an open condition wherein access to the food cavity is available. A ring antenna is supported relative to the base such that it extends generally perpendicular to a base surface of the base and is positioned forward of the food cavity. The ring antenna defines a circumferential ring with an opening therethrough and contains an RFID coil over at least a portion thereof about the opening. A motor is configured to move the cover from the closed condition to the open condition upon sensing of a registered RFID identification proximate to the ring antenna.
