Abstract
Device for recognizing coins based on their di-electric surface properties by radiating electromagnetic radiation by a transmitter onto a coin, which is reflected from the surface of the coin and received by a receiver which transforms the reflected electromagnetic radiation into a measuring signal, said signal is then evaluated by an evaluator unit in which a wavelength-selective evaluating signal is generated and compared to wavelength-selective comparison bands.
