Abstract
Techniques are disclosed for protecting communication of an NFC-enabled device by generating one or more blocking signals during an NFC data exchange. The blocking signal(s) can include a similar carrier frequency, modulation type, and/or modulation rate an NFC signal, thereby effectively masking the NFC signal. Furthermore, the blocking signal(s) can have a varying amplitude and/or length, which can further mask when an NFC signal is transmitted.
