TSA Screening is the security process you go through at the airport before you can go to your gate and board your plane. First, you show a TSA officer your boarding pass and identification (for example, a license or a passport). Next, you put all your carry-on items, your shoes and coat in a basket. The basket is placed on the conveyor belt and travels through a machine that is monitored by a TSA agent looking for prohibited materials. After that, you will go through body scanners. Finally, you will pick up your carry-on items, and go to your flight. TSA is now the main security at all airports.
