Abstract:
A device implementing a system for NFC communication with a second device includes an antenna and a processor configured to transmit a pulse signal for detection of another device within proximity of the device, and to detect, in conjunction with transmission of the pulse signal, that a first value of a measurement parameter of the antenna satisfies an initial detection factor. The processor is further configured, in response to the detection, to set a confirmation detection factor for the measurement parameter of the antenna based at least in part on the first value of the measurement parameter of the antenna, to transmit a confirmation pulse signal, and to initiate a second polling for reception of data from the other device when a second value of the measurement parameter of the antenna detected in conjunction with transmission of the confirmation pulse signal satisfies the confirmation detection factor.
