Tuesday's announcement comes as TSA, airlines and airports have grappled with ways to alleviate long airport security lines that began grabbing headlines earlier this year. One of these features is that they use automated belts, which pull the bags through the X-ray scanner.
The automated screening lanes will join a handful of other programs offered at the Miami airport to expedite security and custom processing for travelers.
By collaborations with airports, vendors, airlines, and the counter-terrorism communities, TSA also intends to introduce additional automated checkpoint lanes in order to improve the screening process and minimise wait times.
"Our foremost priority is the security of the traveling public", said TSA Administrator Peter V. Neffenger.
DHS Secretary Jeh Johnson issued a statement Tuesday complimenting TSA and its workforce for a smooth July 4 holiday experience for airline passengers.
In a first in the US, the Transportation Security Administration said Tuesday that it plans to begin using computed-tomography or CT scanners to inspect carry-on bags at one checkpoint in the Phoenix airport by the end of the year.
The checkpoint lines are shorter, but American Airlines and the TSA are trying to shave down that wait time even more. Each bin is equipped with RFID radio frequency identification chip, allowing TSA agents to track each item easily, says the agency. TSA uses CT scanners for checked baggage. The time it takes to go through security is expected to be reduced by nearly a third as suspicious bags will be redirected to a separate area, allowing other bags to continue travelling through the system uninterrupted. If the test, due to be running in Phoenix by year end, works out, travelers would be able to leave their liquids, gels and laptops in their carry-on bags.
Isom told American employees that he expects the CT technology and the automated belts to chip away at long checkpoint waits.
The CT program is being piloted at Phoenix Sky Harbor International airport and could be deployed nationwide if successful.
