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.
