Title: Invisible identity card coding with capacitance arrays - uses three layer elements incorporated in card and encoded by processing complete card
Inventor: GRIMM WERNER
IPC: G06K19/067
Filed: 1976-01-07
Abstract: A method is used for producing an invisible code in an identity card by incorporating within the card a three layer leaf and then processing the entire card so that the leaf becomes a recognisable pattern of capacitances. The three layer leaf consists of a layer of material of high dielectric constant between two thin metallic layers of material. The three layer leaf is incorporated within the identity card during manufacture. To perform the encoding the entire card is subjected to a pattern of strong static fields which destroy the dielectric in a pattern and produce a pattern of capacitances within the card, corresponding to some required code number. This pattern may be read out using alternating fields.
