The Transportation Security Administration (TSA) has finished the deployment of credential authentication technology (CAT) units at the security screening checkpoints of Las Vegas McCarran International Airport (LAS) in the US.

These touchless, automated photo identification scanners, through a secure internet connection, approves passengers’ identity on-screen and authenticates that they are ticketed to travel that day.

CAT is connected with the Secure Flight database and showcases a passenger’s eligibility for pre-screening status, including TSA PreCheck, without showing the boarding pass to the TSA officer.

It tackles problems related to photo identification and boarding pass fraud, enhancing the TSA officer’s ability to verify passenger identification accurately.

In addition, the solution offers better fraudulent document detection capabilities.

TSA Nevada federal security director Karen Burke said: “Any time we can use technology to supplement the work of our security screening force it is a win-win for TSA and travellers.

“We are extremely pleased that LAS has reached the milestone of having CAT deployed throughout the airport. We continue to set the bar high for the use of this type of technology, which streamlines the passenger travel experience and enhances security.”

Currently, LAS features 58 CAT units at security checkpoints.

Passengers under the age of 18 may be asked to present their boarding passes.

Additionally, travellers will be required to check in with their airline before travel and showcase their boarding pass to their airline gate agent prior to boarding.

CAT units can validate numerous kinds of identification such as passports, state-issued driver licences, identification cards and more.

As of now, TSA has installed over 1,350 CAT units at nearly 155 airports in the country.

In September, Fort Wayne International Airport (FWA) in Indiana deployed a new CAT unit at the TSA checkpoint.
