First Claim
Patent Images
1. A mobile communications device including:
- a near field communication (NFC) transceiver capable of operating in a first mode and a second mode, the NFC transceiver being configured to consume less power in the second mode than in the first mode, the NFC transceiver having a load threshold level associated therewith; and
a controller coupled with the NFC transceiver, the controller being capable ofswitching the NFC transceiver to the first mode when a load detected by the NFC transceiver is below the load threshold level, andswitching the NFC transceiver to the second mode when the load detected by the NFC transceiver reaches the load threshold level.

Abstract
A mobile communications device may include a near field communication (NFC) transceiver capable of operating in a first mode and a second mode, where the NFC transceiver has a load threshold level associated therewith. The mobile communications device may further include a controller coupled with the NFC transceiver. The controller may be capable of switching the NFC transceiver to the first mode when a load detected by the NFC transceiver is below the load threshold level, and switching the NFC transceiver to the second mode when the load detected by the NFC transceiver reaches the load threshold level.
