Abstract

The invention discloses an intelligent card with an electronic signature function, and a system and a method for intelligent card transactions. The method includes that A, the intelligent card is connected with a point of sale (POS) machine for receiving a transaction message; B, the intelligent card generates an associated password; C, the intelligent card generates a signature message according to the transaction message and the associated password; D, the intelligent card sends at least the signature message to the POS machine; E, the POS machine receives the associated password generated by the intelligent card and input through press keys, and sends at least the transaction message, the signature message and the associated password to a bank server; and F, the bank server verifies the signature message and the associated password, and executes a transaction operation according to the transaction message after the signature message and the associated password pass through verification. Interaction of data needed in a transaction is achieved through one time connecting of the intelligent card and the POS machine, and the risks that important information is intercepted and captured caused by repeated connecting are reduced, and furthermore safety is improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a smart card with an electronic signature function, a smart card transaction system and a method. Background technique [0002] Nowadays, credit card consumption has become the mainstream. Use the following process to realize electronic signature transactions: [0003] Step S101, the user holds a card to access the POS machine in a non-contact manner; wherein, the non-contact method can be any non-contact method such as radio frequency, Bluetooth, or NFC. [0004] In step S102, the POS machine sends transaction information to the smart card accessed by the user; wherein, the transaction information may at least include account number and amount, and of course may also include transaction details. [0005] Step S103, the smart card receives the transaction information, displays the transaction information, and after the user confirms that the transaction information is corre...
