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.
