Step 1: Open up the camera app. Apple’s iPhones have built-in QR code scanning capabilities, so there’s no need to download a separate scanning app unless you really want to. Ever since iOS 12, there’s even a direct QR code reader in the Control Panel.
Step 2: Position your phone so the QR code appears in the digital viewfinder. The camera app should automatically recognize the QR code. Of course, the right distance and angle can help. The QR code doesn’t need to fill the entire screen, but all four corners should be visible. If your camera is too angled, the app may have trouble recognizing the code, so a straight-on approach is best. Image stabilization technology helps a lot with the shakes, but try to avoid moving too much so the code square stays visible.
Step 3: Launch the code. Your iPhone will not automatically initiate the QR code activity. Instead, a notification bar will pop up at the top of the screen and follow the steps.
