Machine-readable electronic passports with biometric details, such as iris scans
These are arguably the swiftest and best way of proving identity, since they offer unprecedented accuracy and are virtually fraudproof. More than 30 nations are in the process of adopting e-passports, which use built-in computer chips to store the same data found on the photo pages of current passports.
Walk-through detectors that use electromagnetic technology
The faster, more precise alternative to a metal detector scans travelers for prohibited items in seconds. Its technology uses electromagnetic waves (much like an MRI) to spot foreign objects. Already used in countries such as Japan, Spain, and the United Kingdom, they’re now being rolled out at U.S. airports including New York’s JFK International Airport and Los Angeles’s LAX.
