Method trusted terminal, dual-channel cards, anti-clone, chip and an anti-fingerprint-channel attacks

The present application discloses a trusted terminal, dual-channel cards, anti-clone chip, a method and an anti-fingerprint chip channel attacks, trusted terminal includes a main control chip, dual channel card slot, channel isolation member and a communication interface; the dual channel card slot comprises a first channel connector and a second channel connector, a first channel connector to the control chip is connected, a second channel connector channel spacer member is connected, dual channel card slot for inserting a two-channel card; the present invention, a terminal and a trusted dual channel card to replace the conventional IC card migration, with high safety, high availability, low cost, easy to implement and so on. The key safe are: a conventional IC card is easily cloned bank, thereby easily constructed where "indistinguishable", and it is easily intercepted payment password; dual channel card can not be cloned, can prevent the situation "indistinguishable" of and can effectively protect payment security password.
