Could traditional ID cards someday be obsolete?

Alaska Airlines is testing out a biometrics program that scans retinas or fingerprints of frequent travelers who fly out of San Jose International Airport–no driver’s license or boarding pass required.

Aruba Airport just launched a program called—and I didn’t make this up—Aruba Happy Flow. You show your passport once, and then only facial recognition is used after that.

US Customs and Border Protection will collect biometric information from certain flights in up to 10 airports, including LAX, O’Hare, and JFK. Officers will have handheld devices to collect this information when passengers exit the airport.

We’re already seeing biometrics in action with the CLEAR program. You scan your fingerprints or irises for verification and skip right to screening, instead of waiting in line for a TSA agent to inspect your ID.

Let’s just say, the future is almost here.
