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.
