Deutsche Bahn, the train system in Germany, has an innovative new way for commuters to purchase tickets on the go. You can even reserve a seat on the sometimes crowded trains.
After registering with the service, the traveler can visit a mobile site from their cell phone. After specifying the ticket and seat they desire, they receive an MMS (picture message) with a barcode and confirmation of their ticket.
Once on the train, the traveler can show their phone to the conductor, who simply scans the barcode on the screen to verify the ticket.
Besides the convenience, the system reduces lines at ticket booths and eliminates the need for paper tickets and the associated litter problems.
Cool stuff, and another reason to add to The Case for MMS on the iPhone.
