1. A method for protecting readable script formed on at least one face of an object, referred to as a scripted face, comprising:
covering readable script on at least one scripted face of the object with a transparent protective film, which adheres to the scripted face, and the object is associated with at least one microcircuit having at least one antenna for contactless remote reading of authenticating information, which can be delivered by this microcircuit and is designed to permit authentication of at least some of the readable script,
wherein:
the object is associated with at least one antenna referred to as a matching antenna, formed by printing on a support, this matching antenna having at least one zone for electromagnetic coupling with an individual antenna whose dimensions are smaller than those of the matching antenna,
at least one transparent protective film referred to as a security film is employed, which does not carry a matching antenna but carries at least one microcircuit with an integrated individual antenna, referred to as a microtransponder, at a predetermined position so that after the security film has been placed on the scripted face of the object, and for at least one position or state of the object:
the microtransponder permits electromagnetic coupling of the individual antenna with an electromagnetic coupling zone of a matching antenna associated with the object,
the microtransponder does not mask any essential part of the readable script,
a security film is applied and adhered to a corresponding scripted face in order to cover readable script and so as to permit electromagnetic coupling of the individual antenna of each microtransponder with a coupling zone and a matching antenna, for at least one position or state of the object, the matching antenna having dimensions designed to permit the remote transmission of information between the individual antenna and a power antenna of a reading device when the object is placed in the field of this power antenna.
