Want to rent a car on your next trip? You may be getting your face scanned in order to do so. 

Hertz car rental is partnering with startup Clear to deploy biometrics to speed up its car rental check-out process. 

The technology is already in place at the Hartsfield-Jackson Atlanta International Airport and the company plans to expand to 40 more locations over the course of 2019. Hertz and Clear have named the partnership "Fast Lane." 

Use of this technology won't be available for everyone, however. The facial recognition is being presented as a perk for those customers with a rewards account with Hertz. If they want to rent a car with "Fast Lane," they simply need to show their face at the biometrics kiosk placed near the exit to check out, which will then match it to their drivers' license and registration information.
