You’ll go through a security check, like you would at an airport. This may include:
emptying your pockets into a tray
taking off your shoes, coat, gloves or hat
being asked to take off or open your belt
walking through an archway detector
being checked by hand or with a handheld scanner
If you’re wearing a head covering for religious or cultural reasons, you can ask for it to be checked with a handheld scanner so you do not have to take it off.
