RFID devices comprising (i) a transponder chip module (TCM, 1410) having an RFIC chip (IC) and a module antenna (MA), and (ii) a coupling frame (CF) having an electrical discontinuity comprising a slit (S) or non-conductive stripe (NCS).

A supply-side non-metallic contactless electrical power connector includes a housing with a metal-free coupling interface for coupling to a non-metallic load connector. A power supply electrically connects to an external power supply. A contactless electrical power transmitter is disposed within the housing and adjacent to the coupling interface. A reed switch is disposed within the housing and enters an activated state when in proximity to a magnetic field generated by the load connector. The reed switch is in electrical communication with the power supply and the contactless electrical power transmitter such that when the reed switch is activated, the contactless electrical power transmitter is electrically connected to the power supply and is enabled to contactlessly transmit electrical power to the load connector, and when the reed switch is inactivated, the reed switch prevents electrical connection between the power supply and the contactless electrical power transmitter.

A communication system performs wireless communication using electromagnetic field coupling between a transmission coupler and a reception coupler and moves at least one of the transmission coupler and the reception coupler so as to change the position in a predetermined direction of the reception coupler relative to the transmission coupler. In the communication system, the greater the distance between an overlap portion where the transmission coupler and the reception coupler overlap as viewed from a vertical direction to the predetermined direction and an input end of the transmission coupler is, the higher the degree of coupling between the transmission coupler and the reception coupler becomes.
