METHOD FOR EARMARKING TWO ELECTRONIC PURSES

摘要

A method for earmarking two electronic purses is provided. It relates to the information security field. The method includes: a CPU card enters the contactless type induction area of the terminal to be electrified and initialized, synchronizes the first electronic purse and the second electronic purse, receives the earmarking initialization command sent by the terminal, performs an earmarking initialization operation and returns a response message of the earmarking initialization command to the terminal; the terminal receives the response message of the earmarking initialization command and sends the data in the response message of the earmarking initialization command to the host computer; the host computer receives the data and saves it and sends the earmarking transaction acceptant message to the terminal; the terminal receives the earmarking transaction acceptant message and sends the earmarking command to the CPU card. The CPU card receives the earmarking command, performs an earmarking operation to the second electronic purse and refreshes the balance of the first electronic purse at the same time, and then returns the response message of the earmarking initialization command to the terminal.
