Abstract
The invention discloses a smart card with an electronic signature function. The smart card comprises a transceiving module, a password generation module, a signature module and a display module; the transceiving module is used for accessing a POS machine, receiving a transaction message and sending the transaction message to the signature module; the password generation module is used for generating a joint password and sending the joint password to the signature module and the display module; the signature module is used for generating a signature message according to the transaction messageand the joint password, and at least transmitting the signature message to the POS machine through the transceiving module; and the display module is used for displaying the joint password, so that auser inputs the joint password into the POS machine to complete the transaction. According to the smart card with the electronic signature function provided by the invention, the interaction of data required by the transaction is completed through one-time access of the smart card and the POS machine, the risk that important information is intercepted caused by multiple times of access is reduced,and the safety is improved.
