Abstract

The invention discloses a trading method and a trading system of a smart card with an electronic signature function, wherein the trading method includes: accessing the smart card with the electronic signature function to a terminal, and the smart card receiving a trading message; the smart card generating an associated password; the smart card generating a signature message according to the trading message and the associated password; the smart card at least sending the signature message to the terminal; the terminal obtaining a verification password, verifying the signature message and the verification password and sending a trading instruction to a background system server after the verification, wherein the verification password is the associated password input through buttons of the terminal, or the associated password obtained through information displayed by smart card scanning of the terminal or the associated password obtained from the smart card through the terminal in a non-contact communication mode; and the background system server executing trading operation according to the trading instruction. The interaction of needed data of the trading is completed through one-time access of the smart card and the terminal, the risk that due to repeated access, important information is intercepted and captured is reduced, and the safety is improved.

Description

Technical field [0001] The invention relates to the field of electronic technology, in particular to a smart card transaction method and system with electronic signature function. Background technique [0002] Today, 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; the non-contact manner can be any non-contact manner such as radio frequency, Bluetooth, NFC, etc. [0004] In step S102, the POS machine sends the transaction information to the smart card accessed by the user; where the transaction information may include at least the account number and the 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 correct, receives the confirmation ...
