Abstract:
An apparatus and method is disclosed to optimize power consumption in a NFC environment. A first NFC capable device provides a polling command to a second NFC capable device. The second NFC capable device provides a response to the polling command. The first NFC capable device provides a read command to the second NFC capable device. The second NFC capable device provides a response to the read command that indicates an overvoltage condition is present. The first NFC capable device adjusts a power level that is to be used to transmit further commands when the overvoltage condition is present.
