An accessory for a user equipment, the accessory comprising: a housing that is configured to be slid on the user equipment in order to be attachable at a stored position relative to the user equipment; and a near field communication circuit attached at a location on the housing and configured to become powered by inductive coupling to signals emittable by another NFC circuit within the user equipment to temporarily operate to transmit data to the other NFC circuit within the user equipment while the NFC circuit is provided to pass over the other NFC circuit and is provided to inhibit operating to transmit data while the housing is provided to be at the stored position, wherein the NFC circuit comprises: a pair of antennas (108a, 108b), each antenna is configured to be inductively coupled to the other NFC circuit within the user equipment; a transceiver configured to be powered by at least one of the pair of antennas (108a, 108b) to operate to transmit data through at least one of the pair of antennas (108a, 108b) to the other NFC circuit within the user equipment; and wherein the NFC circuit further comprises a signal comparator and charging circuit connected to the pair of antennas (108a, 108b) and configured to prevent the transceiver from transmitting data to the other NFC circuit within the user equipment until subsequently triggering the transceiver to transmit data to the other NFC circuit based on comparison of relative levels of signals from the pair of antennas (108a, 108b). a housing that is configured to be slid on the user equipment in order to be attachable at a stored position relative to the user equipment; and a near field communication circuit attached at a location on the housing and configured to become powered by inductive coupling to signals emittable by another NFC circuit within the user equipment to temporarily operate to transmit data to the other NFC circuit within the user equipment while the NFC circuit is provided to pass over the other NFC circuit and is provided to inhibit operating to transmit data while the housing is provided to be at the stored position, wherein the NFC circuit comprises: a pair of antennas (108a, 108b), each antenna is configured to be inductively coupled to the other NFC circuit within the user equipment; a transceiver configured to be powered by at least one of the pair of antennas (108a, 108b) to operate to transmit data through at least one of the pair of antennas (108a, 108b) to the other NFC circuit within the user equipment; and wherein the NFC circuit further comprises a signal comparator and charging circuit connected to the pair of antennas (108a, 108b) and configured to prevent the transceiver from transmitting data to the other NFC circuit within the user equipment until subsequently triggering the transceiver to transmit data to the other NFC circuit based on comparison of relative levels of signals from the pair of antennas (108a, 108b). a pair of antennas (108a, 108b), each antenna is configured to be inductively coupled to the other NFC circuit within the user equipment; a transceiver configured to be powered by at least one of the pair of antennas (108a, 108b) to operate to transmit data through at least one of the pair of antennas (108a, 108b) to the other NFC circuit within the user equipment; and wherein the NFC circuit further comprises a signal comparator and charging circuit connected to the pair of antennas (108a, 108b) and configured to prevent the transceiver from transmitting data to the other NFC circuit within the user equipment until subsequently triggering the transceiver to transmit data to the other NFC circuit based on comparison of relative levels of signals from the pair of antennas (108a, 108b).
