    Abstract: The invention is a method of managing communication between a portable device and a contactless reader able to communicate using a first wireless technology configured to communicate in a short-range mode. The method comprises the steps of: —establishing a first channel between the contactless reader and a wireless unit, —establishing between the wireless unit and the portable device a second channel using a second wireless technology which is configured: —to operate with a range greater than that of said first wireless technology, —to detect the position of the portable device with respect to the wireless unit, —to handle an anti-collision phase, —establishing a bridge between the contactless reader and the portable device through said first and second channels only if the detected position of the portable device matches with the contactless reader.

    Abstract: The invention relates to a method of reading RF transponders disposed in one and the same magnetic interrogation field, in which a magnetic coupling of the transponders is ensured with a passive resonant circuit during reading. The method is distinguished in that the passive antenna of the resonant circuit is associated with at least one transponder antenna, and the passive resonant circuit is tuned in such a way that the resonant frequency resulting from the association corresponds to one of the frequencies of the emission side bands of the transponder to be read. The invention also relates to the system corresponding to the method, a transponder structure and an object containing the transponder, in particular a travel document.
