Better security protection with biometric identifications, but it may affect the boarding time.

Quote:
Lufthansa and Siemens has successfully tested a biometric process for check-in and boarding at the Airport. The system identifies passengers from their fingerprints.

After a passenger’s finger is rolled over an optical reader unit, the system converts the fingerprints’ characteristics into a 2D code which the reader prints on the boarding pass. Just before boarding, the fingerprints are again scanned by a reader and compared with the barcode. The data is erased after the passenger checks in.
