ABSTRACT:
A method and system of transmitting electronic value information between terminals. The method includes the steps of: authenticating each other between a transmission source terminal and a destination terminal; sharing authentication for common information obtained by the authentication; encrypting data including the electronic value information to be transmitted; transferring the encrypted electronic value information to the destination terminal when the terminals are recognized with each other; temporarily invalidating the electronic value information left in the source terminal; transmitting reception confirmation to the source terminal when the destination terminal completes reception of the electronic value information; deleting the invalidated electronic value information left in the source terminal when the reception confirmation is received by the source terminal; transmitting validation information to the destination terminal after the deletion of the electronic value information in order to validate the electronic value information; receiving and validating the electronic value information by the destination terminal.
