Online creation of tickets for ticketed events

摘要

Methods and systems for creating online tickets enable a user to purchase a ticket over the Internet and to redeem the ticket for admission at a ticketed event. Barcodes are printed on the tickets and contain unique authentication information. Dual barcoding enables authentication information of the ticket to be read when one of the barcodes is damaged or cannot be read. A copy of the authentication information is stored in a database and is used to verify the authenticity of a ticket when it is presented for redemption at a ticket event. Authenticity of the ticket is verified by comparing authentication information on the ticket with authentication information accessed from the database. To discourage counterfeiting, the tickets contain transparent images that when photocopied become opaque and prevent a ticket from being redeemed.
