Abstract
A method, an apparatus, and a computer program product for wireless communication are provided in connection with enabling a NFC-enabled device to discover and/or communicate with a TTF device. In one example, a NFC enabled device is equipped to initiate a RF field that is not modulated by the NFC-enabled device as part of a technology detection process, monitor the RF field for at least a portion of a wait duration, determine whether, during the wait duration, the RF field is modulated in a manner consistent with modulation characteristics of a NFC technology, and terminate the technology detection process upon the determination that the RF field is modulated a manner consistent with modulation characteristics of the NFC technology.
