Launch the camera app on your smartphone. Most modern smartphones have a built-in QR code scanner in their camera.
Hold your camera so that the QR code is within the frame on your phone’s screen. Make sure it’s centered and well-lit.
Your camera should recognize the QR code automatically and display a notification or a link on your screen. Tap on the notification to proceed.
Depending on the specific parking system, the QR code may lead you to a mobile app, a website or provide parking instructions. Follow the on-screen instructions to complete the packing process.
