Carnival Cruise Line is using facial biometric technology to expedite the debarkation process for its guests. Nine of Carnival’s 14 U.S. homeports are using this technology, and the debarkation process has been expedited by an average of 30 percent.

The technology compares the guest’s image to their passport or visa photo to verify their identity with over 98 percent accuracy. Guests who prefer to opt out of the facial biometric process can request a manual document check from a CBP Officer.
