The invention discloses a smart card swipe machine and an information exchange method. The smart card swipe machine is characterized in that the swipe machine is firstly initialized by a first-stage authority card, and is secondly initialized by a third-stage authority card which records second-stage authority card passwords, equipment user codes, batch numbers and card number information, and then a fourth-stage authority card is identified; and simultaneously, the smart card swipe machine utilizes a mobile communication module in the swipe machine to send short message information to a server. The mutual certification of information among multi-stage authority cards, a card dispenser and the swipe machine is combined with mobile communication function to master the condition of service of user terminal equipment in real time, thereby ensuring the authenticity of current information interaction and improving the reliability of safety certification.
