PHILADELPHIA (CBS) — The Transportation Security Administration will be opening up a temporary enrollment office at Philadelphia International Airport, offering people a chance to sign up for expedited security screenings for a fee.

While walk-ins are welcome, appointments can be made online for the TSA Pre-Check program.

After an $85 payment, an interview and background check travelers who are deemed “low-risk” will be given a “known traveler number” that will allow them to go through security lines quicker, and go through without being required to take off shoes or light jackets, or remove laptops and liquids from their carry on bags.

The temporary location is at the airport’s Terminal B in the baggage claim area, and is open from 8 a.m. to noon and from 1 to 5 p.m. now through Friday.

This is in addition to two permanent enrollment centers in the city. One is on North Delaware Ave, the other is on Chestnut Street.
