CA 2224905
A device for contactless data exchange with an electronic label that does not have its own power supply is disclosed. The device comprises means for receiving a modulated signal (Sr) from the label, which means further comprise means (221) for retrieving data (V) on the distance (Di) between the label (100) and the device (200) from said signal from the label. The device may be used in contactless identification systems.
L'invention concerne un dispositif d'échange d'informations sans contact avec une étiquette électronique, cette étiquette étant dépourvue d'alimentation propre, le dispositif comportant des moyens de réception du signal modulé (Sr) émis par l'étiquette, qui comportent en outre des moyens d'extraction (221) d'une information (V) représentative de la distance (Di) entre l'étiquette (100) et le dispositif (200), à partir du signal émis par l'étiquette. Applications aux systèmes d'identification sans contact.
