Method and device for protecting text for reading

摘要

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 ).
