Qantas membership cards now have integrated RFID tags which can be used in place of a paper boarding pass to drop baggage and alight the plane. The only requirement is that you must check in online within 24 hours of your flight. In fact, the bag drop is particularly clever. Qantas give their frequent flyers robust bag tags with integrated RFID chips, so at the airport you just scan your card and drop your bag. If you don't have a bag tag, it prints you a "classic" adhesive tag -- with an embedded RFID chip! I think the paper ticket's days are numbered.
