Abstract
A system for making a remittance between persons and making payments offline, and for securely being able to conduct these transactions is disclosed. A participant terminal stores verified TX information to which is added a verified TX object, which represents a transaction (TX) and has been verified by a verifier. Each participant terminal stores unverified TX information to which is added an unverified TX object, which represents a TX and has not been verified by a verifier. When a TX arises between a first participant and a second participant, the first participant terminal and the second participant terminal mutually retain the same unverified TX object group including the unverified TX object of that TX. When the first participant terminal is online, verification of the unverified TX object is requested, and, when the verification is successful, that object is added to the verified TX information as a verified TX object.
