Abstract
An electronic ticket management system includes an event organizer for planning an event, an electronic ticket seller for distributing electronic ticket information which authenticates the right to attend the event, an information storage chip for storing the electronic ticket information, and an electronic ticket platform center for managing the distribution of the electronic ticket information. The electronic ticket platform center forms an electronic ticket information master based on event information registered by the event organizer, and relates ticket issuing information registered by the electronic ticket seller to the electronic ticket information master. The electronic ticket platform center also issues the tickets by writing the electronic ticket information into the corresponding information storage chip based on ticket issuing information. A determination as to whether the user is permitted to enter the event venue is made according to the integrity of the event information stored in the information storage chip.
