Abstract: The invention relates to the data processing technology, and in particular, to a method for processing failure to reading non-contact IC card data by a transaction terminal and an apparatus for implementing the method.

Abstract: The present invention discloses a device and method for security information interaction. The device for security information interaction includes: an interface circuit, configured to connect the device for security information interaction to an internet terminal; an information input unit, configured to allow user to input security information; a secure encryption/decryption unit, configured to store and process the security information; an information reader, configured to read information data from an external information carrier; wherein the secure encryption/decryption unit processes the security information in connection with the information data, and complete a business function on the secure channel through the interaction with the security information processing server.

Abstract: The present invention discloses a system and method for security information interaction. The system for security information interaction comprises a device for security information interaction configured to obtain the security information input by a user and the information data read from an external information carrier, and configured to establish a secure channel between it and a security information processing gateway through an internet terminal to perform a business function. The device for security information interaction is able to perform business functions that do not require online processing. The system and method for security information interaction disclosed herein improves the flexibility and efficiency of the information processing system and enhances the balance of the operating load, and increases the security of the information processing system.

Abstract: A payment system and method of IC card and a multi-application IC card as well as payment terminal are proposed in the present invention. The terminal and the IC card perform off-line data authentication using an asymmetric key algorithm during an off-line transaction, and if the transaction is not approved in manner of off-line, the terminal and the IC card performs an on-line transaction via a host. Therefore, the payment system and method of IC card and the multi-application IC card as well as payment terminal disclosed in the present invention can be used both in machinery without on-line transaction environment and in standard merchant machinery with on-line transaction environment.
