  • Document having light-transmissive, electrically conductive authenticating interior layer
    Patent number: 4591189
    Abstract: A standardized document such as a credit card has a thin, light-transmissive, electrically conductive interior layer, the impedance, capacitance, or conductance of which can be sensed to indicate the authenticity of the document.
