Abstract: A first near field communication (NFC) circuit includes an antenna, a charging circuit, a transceiver circuit, and a transmission delay circuit. The antenna is configured to inductively couple to signals emitted by a second NFC circuit. The charging circuit is configured to output power provided by the inductive coupling through the antenna to the signals emitted by the second NFC circuit. The transceiver circuit is configured to be powered by the charging circuit to transmit data for receipt by the second NFC circuit. The transmission delay circuit is configured to be powered by the charging circuit and control the transceiver circuit to delay transmission of the data until expiration of a defined delay time after the transceiver circuit has become sufficiently powered on to operate to transmit the data. Related accessories for user equipment, user equipment, and methods are disclosed.

Abstract: An accessory for a user equipment (UE) includes a housing and a near field communication (NFC) circuit. The housing is slid on the UE to become attached in a stored position relative to the UE. The NFC circuit is attached at a location on the housing and configured to become powered by inductive coupling to signals emitted by another NFC circuit within the UE to temporarily operate to transmit data to the other NFC circuit within the UE as the accessory NFC circuit passes over the other UE NFC circuit while the housing is being slid on the UE before reaching the stored position relative to the UE. While the housing is in the stored position relative to the UE, the NFC circuit may be configured to be inhibited from transmitting data to the other NFC circuit within the UE irrespective of whether the other NFC circuit within the UE is emitting signals to attempt to provide inductive coupling to the NFC circuit.
