Abstract
A radio-frequency identification device of the non-contact type, suitable for fixing to an object to be identified that includes a module with at least one electronic chip and at least one electrical and/or magnetic so-called primary antenna used to supply signals to the at least one electronic chip, and an electrical and/or magnetic so-called secondary antenna. The secondary antenna is a conductive element that forms part of the object or is produced by modifying a constituent of the object, the secondary antenna being coupled to the primary antenna without an electrical connection.
