If the identification information is different, the validity identification information also has a different relationship, so even if you try to steal a validly purchased electronic ticket and record it on another card and use it, the validity identification information does not match, so the illegal ticket Can be easily found.

[0035]

[Effect of the Invention] There are various tickets today, such as tickets for theaters, stadiums, etc., as well as tickets for transportation such as trains, airplanes and ships, and their reserved seat tickets. ing. In order to purchase these tickets, the tickets are sold at a sales window of a transportation facility or a theater or a ticket sales window called a so-called play guide which performs various types of ticket sales, and a ticket is received. If you live in a remote location where there is no ticket sales counter nearby, call the sales counter or call F
There is also a service that makes a reservation for purchase by AX or other means, remits the price, receives payment by mail after confirming payment, but the ticket issuing procedure is complicated and it takes some time to receive the ticket However, this is not always a convenient method. In addition, in window sales, tickets cannot be purchased unless it is during business hours, and it cannot be said that the ticket sales service is sufficient. However, by digitizing a paper ticket conventionally issued with a special paper according to the present invention, it is possible to provide a system for purchasing an electronic ticket at any time and from anywhere using, for example, a personal computer at home and a communication line. It is assumed that. Also, by using the validity identification information of the ticket when issuing the electronic ticket, it is not necessary to inquire the system of the ticket issuing company to determine whether or not the electronic ticket is correct when the ticket is used. As long as it is prepared, entrance, boarding and boarding gates and ticket inspection are possible at any place. For example, it is very effective for entrance ticketing at temporary and temporary venues such as circuses, and ticket inspection of reserved seats in trains, and its mobility can be applied to a wide range of tickets. It is possible to provide a system that is much more convenient for a ticket issuing company and a ticket purchaser than before and that is extremely safe against fraud such as forgery or duplication.
