SMART CHIP AND METHOD FOR SMART CHIP DATA COMMUNICATIONS

摘要

Disclosed are a smart chip and a method for smart card data communications, for use in increasing the smart chip resource utilization rate. The smart chip comprises at least two communication interfaces. The data communication method comprises: the smart chip card receiving via a first communication interface an application protocol data unit (APDU) command transmitted by a terminal; upon confirmation of the APDU command being a process command for the smart chip card, processing correspondingly, and returning the process result to the terminal via the first communication interface; otherwise, transmitting via a second communication interface the APDU command to a smart card connected to the second communication interface, and via the first communication interface, returning the second processing result returned by the smart card via the second communication interface.
