RFID and luggage tags
"..passengers submit their luggage at the check-in counter, as before, and the ground staff attaches a paper strap to it. But the strap now has an integrated radio chip with antenna, microprocessor and a memory to record all the relevant information."
"The system uniquely identifies the radio chip even when it is situated in an awkward position because, unlike a bar code, it does not require optical contact to be scanned."
"The system, which has been exhibited at the Terminal Passenger Expo in Amsterdam, scans RFID chips with a success rate of 99.9 percent — far higher than that of the bar codes previously used."
