Device and method for safety information interaction and IC card for safety information interaction

The invention provides a device and method for safety information interaction and an IC card for safety information interaction. The method for safety information interaction comprises the following steps that (A1) the safety information interaction device transmits the first part of safety information input by a user to the IC card, (A2) the IC card verifies the first part of the safety information according to the second part of the safety information and a check code, generates a response according to the verification result, and transmits the response back to the safety information interaction device, and (A3) the safety information interaction device generates a data interaction request on the condition that the response indicates verification success, and sends the data interaction request to a data processing server for finishing subsequent data processing. The device and method for safety information interaction and the IC card for safety information interaction have high safety.
