Abstract:
A method can be used for detecting a potential presence of an object by a reader capable of mutually communicating via a contactless communications protocol. An antenna of the reader transmits a magnetic field on a carrier signal having a sub-carrier modulated by a first data sequence. The modulated sub-carrier is non-interpretable by the object. The antenna of the reader receives a signal resulting from the transmission. The reader demodulates the sub-carrier of the resulting signal so as to extract a second data sequence from the resulting signal. The first data sequence and second data sequence are correlated and the potential presence or absence of the object is determined based upon the result of the correlating.

Claim (Index 14):
A reader, capable of communicating with an object by a contactless communications protocol via an antenna, the reader comprising:\n a modulator configured to modulate a sub-carrier by a first data sequence to generate a modulated sub-carrier, the modulated sub-carrier being non-detectable by the object; a transmitter configured to transmit, via the antenna, a magnetic field on a carrier signal comprising the modulated sub-carrier; a receiver configured to receive a resultant signal on the antenna in response to transmission of the magnetic field; a demodulator configured to demodulate the resultant signal using a demodulation signal having a frequency of the sub-carrier to generate a second data sequence; a correlator configured to perform a correlation between the first data sequence and the second data sequence; and an analysis circuit configured to detect a potential presence of the object or an absence of the object based upon on a result of the correlation.
