The electronic verification machine (242) electronically couples with the circuit and applies an excitation signal such as an AC signal having a predetermined frequency through a read head (230) to the document (100) whereby the document includes a printed conductive material thereon. A sensor array (226A-H) in combination with detection circuit in the electronic verification machine (242) then generates a detection signal in response to the excitation signal which can both represent the location and the characteristics of the electrically printed material on the document. By storing the location of the conductive material on the document in a memory (224), the shape (238) of the conductive material can be determined. The electronic verification machine can also be used to stigmatize the document by applying a signal to the electronic circuits having sufficient strength to alter the electronic circuit.

Cette machine (242) de vérification électronique est couplée de manière électronique au circuit et elle applique un signal d'excitation, tel qu'un signal en courant alternatif possédant une fréquence déterminée, à travers une tête (230) de lecture, en direction du document (100) sur lequel est imprimé un matériau conducteur. Un groupement (226A-H) de capteurs, combiné à un circuit de détection monté dans ladite machine (242), produit ensuite un signal de détection en réponse au signal d'excitation, ces deux signaux pouvant représenter l'emplacement et les caractéristiques du matériau imprimé de manière électrique sur le document. En conservant dans une mémoire (224) l'emplacement du matériau conducteur imprimé sur le document, on peut déterminer la forme (238) dudit matériau. On peut également utiliser la machine de vérification électronique pour "stigmatiser" le document en appliquant aux circuits électroniques un signal qui soit suffisamment puissant pour modifier le circuit électronique.
