Abstract
A method and a device for protecting text for reading (23), arranged on at least one written face (22) of an object (25). The object (25) is connected to at least one matching antenna (12), produced by printing on a support (11) and having at least one electromagnetic coupling zone (14) with an individual antenna of smaller dimensions. At least one security film (3), not provided with a matching antenna (12) but with at least one individual integrated antenna microcircuit called a microtransponder (7), is applied to cover the text for reading (23) for which authentication information may be delivered using the microtransponder (7).
