Admission Tickets as Text Messages
lee1 writes to tell us that InfoWorld is reporting that Smartmachine and their partner Skidata have developed a new way to allow customers to purchase and receive tickets to events. The new ticketing system allows users to "have a ticket sent to their mobile phone via SMS (Short Message Service) in the form of a 2D (two-dimensional) bar code. At the gate, they slide their mobile phone display showing the bar code by a bar code reader." The new technology also claims to help combat the counterfeit, pilferage, and repeat use that can be such a problem for paper tickets.
I've seen the same system in use for public transport tickets in Helsinki. People send an sms to some number, and the fare is deducted from their phone bill. As a proof of purchase the get a text message, which can be shown to the conductor on ticket controls..
The Koreans have been doing this for years. To promote it they gave you a discount if you used the cell phone technique.
It makes a lot of sense. It's convenient to order the tickets, also via cell phone, and then you don't have to wait in line. And everyone there has a cell phone.
Funfact: In South Korea when you buy a movie ticket, you can buy a particular seat, like at a sports game.
Presumably, the "tickets" are generated uniquely by some mechanism that's "difficult" to hack. And once you go through the turnstile, your "ticket" is scanned and the database to which the scanner is connected marks it as used. This is no different from paper tickets with barcodes that are scanned at the gate.

Ticketmaster actually charges MORE for you to print your own tickets. How ridiculous is that? It's cheaper to go to their counter, use their clerk's time, and use their ink/paper.. I didn't realize that it cost so much to send PDFs out by email. They must be using Adobe Acrobat Professional or something..
It doesn't matter what the phone uses 'over the air', your SMS can still be read out of the CCITT 7 which is beamed as part of a bog standard timeslot in a completely unencrypted T1/E1 between the cell station and the exchange. (Or mulitplexed in some other standard manner) Encryption usually only happens between the phone and the cell station, nowhere else along the chain.
It'll cost a small chunk for the equipment, though all of it can be obtained off the shelf. Spec An, RX equipment, downconverters, modems, digital capture card, pc.
