The present disclosure relates to a near-field communications circuit, comprising: a near-field communications controller; a matching network; and a switch, wherein the switch has one or more inputs, coupled to one or more outputs of the near-field communications controller via the matching network, and a plurality of outputs, each output being suitable for coupling the switch to a corresponding one of a plurality of near-field communications antennas.

Near-field communications circuit

A Near Field Communication (NFC) reader can wirelessly cooperate with a rectangular prism-shaped transponder having an NFC transponder antenna. The NFC reader includes an NFC controller, a matching network coupled to the NFC controller, and a receptacle capable of at least partially holding the transponder. The receptacle has a bottom wall, a lateral wall and a shape designed such that the transponder cannot be placed in the receptacle in a direction where the NFC transponder antenna is parallel to the bottom wall. The receptacle includes first and second NFC reader antennas located in two non-parallel parts of the lateral wall and a connection coupling the first and second reader antennas to the matching network.
