Abstract
In 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, provision is made for at least one identified zone of said reply card to be provided with a succession of signs printed with a conductive ink, and for a determined physical action to be taken that consists in perforating at least one of said identified zones so as to detach at least a portion of said succession of signs printed with a conductive ink from the 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.
