The Nine Zero hotel in Boston has upgraded its security with an iris-scanning system developed by South Korean LG Electronics and also used in high-security areas at airports.

Cameras and computers capture the unique patterns of an individual iris when they check in at the hotel. Once digitized, the images are stored in a database with other information about the guest — such as name and which room or suite they’re staying in.

Cameras at the main entrance and outside every guest room control the locks on the doors. To unlock a room, guests, employees, and other pre-screened individuals have to peer into the cameras while a computer looks for a matching profile.

How well the iris system worked during the convention is still under review. But the group that owns the Nine Zero says the technology could appear in its other luxury hotels, resorts and golf clubs throughout the United States.
