Only the first scan of the barcode on your ticket will be allowed entry. Make sure you keep your ticket safe and do not reveal/ disclose the barcodes unnecessarily. If more than one copy were to arrive, the barcode scanner will alert the attendant that the ticket has already been scanned. In the event of a dispute, the ticket holders will be asked to produce their proof of purchase from Ticketmaster as well as verification of the Ticketmaster account used for the purchase. 

It is the responsibility of the ticket holders to keep their tickets safe from potential disclosure of sensitive information such as barcodes and/ or ticket purchase order number.
