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 10):
A method for detecting a potential presence or an absence of an object by a reader, the method comprising:\n modulating, by the reader, a sub-carrier by a first data sequence to generate a modulated sub-carrier; transmitting, by an antenna of the reader, a magnetic field on a carrier signal having the modulated sub-carrier, the modulated sub-carrier being non-detectable by the object and non-interpretable by the object as being a transmission of information from the reader, wherein the modulated sub-carrier has a frequency corresponding to a reference frequency associated with a contactless communications protocol; receiving, on the antenna of the reader and in response to the transmitting, a resultant signal; demodulating, in the reader, the resultant signal using a demodulation signal having the reference frequency to generate a second data sequence from the resulting signal; correlating the first data sequence with the second data sequence; and detecting the potential presence or the absence of the object based upon a result of the correlating.
