QR Code Access Wing Barrier for Fast Self Service Passage Control Product Description Manual ticket checking slows every entrance and cannot guarantee that one ticket is used by only one person. This wing barrier enables fast QR code passage for indoor playgrounds, trampoline parks, children amusement parks and similar venues, working with customised QR code wristbands. Visitors simply scan the wristband QR code when entering and exiting, so no staff intervention is required
