An electronic token system includes a token receptacle and a portable token. The receptacle includes an RF transceiver antenna. The portable token includes a RF data exchange circuit, an enclosure for enclosing the exchange circuit, and a magnetic coupling member having an antenna in communication with the exchange circuit. The antenna is mounted in a projection extending radially from the token enclosure. A keyway is provided in the receptacle for receiving and guiding insertion of the token. The keyway is configured to receive the token in an insertion position in which the magnetic coupling member is not operably coupled to the receptacle's RF transceiver antenna and, upon token rotation, to guide the token to an activation position in which the magnetic coupling member is operably coupled to the RF transceiver antenna. The present disclosure further relates to improved security and RF dissipation and decreased RF leakage of the token system.
