ELECTRONIC MONEY VALUE CONVERSION DEVICE, SYSTEM, AND ELECTRONIC MONEY VALUE CONVERSION METHOD

摘要

The present invention is relative to a system enabling a through operation between a mileage system and an electronic money system. The mileage system is such a system in which mile points as distance points corresponding to the flight distance of an aircraft are accumulated and exchanged for boarding tickets and other services. An IC card (230) having stored a wallet number in it is used. The wallet number and a mileage number are managed in a correlated fashion. Responsively to a request from a user, reference is made to an electronic money value ledger (222), matched to the wallet number, while reference is also made to a mile point ledger (122), matched to the mileage number. A preset number of the mile points are changed over to an electronic money value and, depending on changed-over results, the electronic money value ledger is subjected to integration processing, while the mile point ledger is subjected to deduction processing. <IMAGE>
