Method of processing reply cards

A reply card enabling a recipient of said reply card to answer at least one request made by a sender of said reply card by taking a determined physical action on at least one identified zone of said reply card, wherein said at least one identified zone is provided with a succession of signs printed with a conductive ink, and wherein said determined physical action consists in perforating at least one said identified zone so as to detach at least a portion of said succession of signs printed with a conductive ink from said reply card, the effect of said detaching being to prevent a radio-frequency read device possessed by the sender from receiving the answer associated with said succession of signs printed with a conductive ink and detached by the recipient.

A module of a mail-handling machine, which module is suitable for enabling a reply card returned by its recipient to its sender to be processed by said sender, and in which reply card said recipient has answered at least one request made by said sender by taking at least one determined physical action on at least one identified zone of said reply card, wherein said module includes a radio-frequency analysis device for using radio-frequency analysis of said reply card to determine whether or not said at least one identified zone is provided with a succession of signs printed with a conductive ink, the radio-frequency image of the positions of the signs making it possible to interpret the answer given by said recipient to said at least one request made by said sender as a function of whether or not said succession of signs printed with conductive ink in said at least one identified zone is present.
