ABSTRACT:
A safety paper with an embedded electronic circuit (1, 4, 7) is used to create more effective forgery-proof securities such as bank notes. In order to check authenticity, a carrier-frequency signal is transmitted to the circuit and an output signal representing an authenticating feature is emitted from raid circuit in response to said input signal and detected.
