I've got news, folks -- it doesn't stop the scalpers. They are using corporate Visa purchasing cards and fake id's to buy the tickets, then meeting buyers at the venue to escort them to the gates. (The person on record as the buyer must have the CC *and* a photo ID -- all with the same name -- in their name for the CC's to be scanned at the gates, but that person does not have to actually be the person who uses the tickets.)
As for cash purchases, you're out of luck. They are not taking cash for these. Gift cards issued by Ticketmaster, Amex, Mastercard or Visa will not be accepted, either.
