A method and system for localizing an object among a set of objects, each equipped with an improved RFID tag. The tag includes an RFID chip, an antenna, a visual indicator, an AC/DC converter, and at least a pair of conductive surfaces adapted for receiving power from an external source and for powering the electronic chip according to capacitive coupling. Each conductive surface of the pair is designed to form the half of a capacitor, the capacitor being formed when the electronic tag and a similar electronic tag are attached to a neighboring adjacent object. To localize an object, an RFID reader is used, fed with the identifier of the object to be localized. All the capacitively coupled RFID, in the RFID reader range, receive a reading trigger that carries the identifier. The RFID tag compares the received identifier with its own identifier and if they match, then the capacitively coupled RFID reacts by providing a visual indicator; otherwise, if they do not match, the capacitively coupled RFID does not react.
