A touchless fingerprint sensor device developed by the Huntsville-based biometrics firm AOS is being tested in Amsterdam's Schiphol Airport.The Advanced Optical Systems (AOS) trial deployment is part of European Union pilot program testing new technologies for border security.The firm's ANDI OTG Zero-Contact Fingerprint sensor captures users' fingerprints as they wave their hands through a scanning zone, with staff saying it can process 3,000 passengers an hour.”As you pass the device you just wave your hand in front of it and it gets all four fingerprints instantaneously,” AOS business development director Christopher Centamore told Tech Alabama, adding that the company is currently working to install this product at domestic airports.Travellers will simply need to enroll in the TSA Precheck program for your fingerprints to properly register with the ANDI system.”Instead of standing in a long line in the airport, waiting for that individual to look at everyone's individual driver's license and check their boarding pass, you just walk past, wave your hand in front of the device, and instantly you're identified as who you are, and that you're allowed to be there,” explains Centamore, who also claims this biometric method helps safeguard sensitive information.”The information you're really trying to protect is your name, your address and your Social Security number,” says Centamore, “If that can be hidden behind your biometrics, that's where we see the privacy protection.”
