touch and travel

Excellent info posted by Timo Arnall on the new eTicketing System Touch&Travel from Deutsche Bahn:

“More details on the service/interaction design:

• By waving your NFC mobile handset over the so called Touchpoint before entering the train, located at the platforms, the system registers the beginning of a trip.
• The ticket is stored on the SIM card inside the mobile phone
• The conductor checks the ticket by scanning the phone with a portable reader.
• Having arrived at the destination, the handset is waved over the Touchpoint again. The system registers the end of your trip. The system processes the data and calculates the correct cost for the distance traveled.
• The passenger is billed once a month”
