A communications system may include a terminal device that may include a housing, and a conductive radio frequency (RF) terminal receiver carried by the housing for receiving an RF signal conducted via contact with a user. The communications system may also include a user device including a portable housing, and a finger sensor carried by the portable housing and that may include RF excitation circuitry for sensing a finger of the user, and for serving as a conductive RF user device transmitter to transmit the RF signal onto the user to be received by the conductive RF terminal receiver. |
