The introduction of new technology is changing the speed and efficiency of traveling. Here are four new advances that will transform the way you travel in 2018

Delta biometrics at lounges

Airlines are always looking for ways to make the user experience more seamless. That’s why Delta Air Lines (DAL) has enabled biometric technology for travelers to gain access to airport lounges. Starting on March 26, Delta Sky Club members who have signed up for CLEAR, can use their fingerprints to enter all 50 U.S. Sky Club locations.

If you don’t have CLEAR, a service that expedites the screening process by verifying your identity using biometrics, you can simply visit one of the enrollment kiosks and sign-up for free. The only caveat is that you must be a U.S. citizen or permanent resident.

Delta says that they tested the fingerprint scanner for under a year, making improvements along the way. Some of the improved features include a new design, ergonomic finger supports to promote successful scans, and sound/light features to make processing easier to understand.

This isn’t the first time the airline has used biometric technology to improve the customer experience. Delta is currently testing biometric boarding experiences, where SkyMiles members enrolled in CLEAR would be able to forego a paper boarding pass in favor of scanning their fingerprint.

Facial recognition

Biometric technology has also been introduced at LAX Airport in Los Angeles, at least temporality. On Feb. 2, the Transportation Security Administration (TSA) launched a three-week trial to experiment with how facial recognition could speed up the security process.

The test includes two gates in the Tom Bradley International Terminal, where passengers scan their passports and boarding passes. The gate instantly verifies that the information on both documents match, and then snaps a photo of the traveler. Newer passports contain a microchip version of your photo, so the gate also compares your new photo with the one stored in your passport. If everything matches, passengers are given a green light. While a TSA agent will still verify passenger identities to make sure no mistakes occurred, the hope is that one day fewer personnel will be needed.

“TSA expects that facial recognition may help reduce dependencies on TSA personnel and expedite security processes, resulting in shorter lines and reduced wait times,” the TSA said in a memo.

For now, the biometric gates will only be used for a few hours each day, but trials like this are becoming more and more popular. Miami International Airport started a facial recognition pilot program last November, and Orlando International Airport (MCO) now allows biometric boarding with facial recognition for British Airways flights to London’s Gatwick Airport. JetBlue also experimented with facial recognition during boarding last June at Boston’s Logan International Airport.
