Abstract:
1. A card discriminating system for identifying whether a card is authentic or not, the card having a surface, N sensing marks being formed on the surface of the card, N being a natural number, the system comprising: a position-based pulse generating module for generating a reference position-based pulse while the card actuates and passes through the position-based pulse generating module, the reference position-based pulse comprising N absolute position-based pulses, each of which corresponding to one of the N sensing marks respectively; at least one sensor for generating a sensing position-based pulse while one of the N sensing marks on the surface of the card passes through the at least one sensor; and a micro-controller unit respectively coupled with the position-based pulse generating module and the at least one sensor, the micro-controller unit being used for receiving the reference position-based pulse and the sensing position-based pulse and for comparing the sensing position-based pulse with each of the N absolute position-based pulses, wherein when the sensing position-based pulse is the same as one of the N absolute position-based pulses, the micro-controller unit identifies the card as authentic, or when the sensing position-based pulse is different from each of the N absolute position-based pulses, the micro-controller unit identifies the card as fake.
