Claim of US Patent No. 9,420,403

1. A mobile phone, comprising:
a near field communication (NFC) radio transceiver included in the mobile phone;
an NFC radio antenna included in the mobile phone; and
a coupling component included in the mobile phone that:
couples the NFC radio antenna to the NFC radio transceiver when selected to a first state, and
decouples the NFC antenna from the NFC radio transceiver when selected to a second state in response to receiving an NFC deactivation
request from a cellular wireless network, wherein the NFC deactivation request is sent in response to an indication that the
mobile phone has been misplaced, and wherein the NFC antenna remains decoupled from the NFC radio transceiver in response
to receiving the NFC deactivation request until an NFC radio system activation request is received from the cellular wireless
network.
