There are three ways to scan the QR code on iPhone: one is to directly scan with a native camera, and then click the pop-up window after aligning the QR code; the second is to quickly enter the scanning interface through the "Scan QR Code" function of the control center; the third is to set a third-party app as the default scanning tool. Common problems include too old system version, insufficient lighting, wrong angles or QR code itself, which can be solved by checking them one by one.

Scanning the QR code is actually quite simple for iPhone, especially after updating from the iOS system, it can be directly identified with the built-in camera. You just need to turn on the camera and aim at the QR code, and the system will automatically pop up the prompt, just click in. However, sometimes it may be difficult to deal with due to unfamiliar operation or setting problems. The following common situations and solutions can help you scan the code more smoothly.

Scan the QR code directly with the camera

This is the most commonly used and fastest method. The native iPhone camera has supported direct recognition of QR codes since iOS 11.

• Open the "Camera" App (not a dedicated app for scanning codes)
• Point the lens to the QR code to keep it stable and have sufficient light
• The system will display a pop-up window on the screen, and click to jump to the link

Note: If there is no response, it may be that your camera permissions or the system version is too old. Check whether the system has been updated or the relevant settings have been turned off.

If the camera cannot scan, try "Scan the QR code" in the control center

Sometimes you don’t want to keep on the camera, or you want to enter the QR code scanning interface faster, you can use this method.

1. Go to Settings → Control Center
2. Find the "QR code scanner" and click the plus sign in the previous one to add it
3. Pull down the control center and click on the QR code icon to open a special code scanning interface

This method is more suitable for use in specific scenarios, such as when you are paying or connecting to Wi-Fi, you want to scan the code quickly.

Use third-party apps as default scanning tool

If you are used to scanning codes with WeChat, Alipay or other apps, you can also set them as the default scanning method.

• Find the "Scan" function in the App
• When you use it for the first time, the system may prompt you whether to allow the app to process QR codes.
• After agreeing, you can scan the QR code directly through this app.

However, it should be noted that not all apps support system-level integration, and some still need to be opened manually before they can be used.

Frequently Asked Questions and Small Details

Sometimes you clearly aim at the QR code, but you just can't scan it out, maybe because:

• The QR code is too small or blurry, try to get closer or enlarge
• The light is too dark, causing the camera to not recognize it
• iPhone angle is incorrect, try to keep vertical alignment as much as possible
• The camera lens is dirty, wipe it again and again

Another thing that is easy to ignore is that some of the QR code content is not web page links, but text, business cards or Wi-Fi information. At this time, you need to select "View Content" to see the specific information.

Basically, these are the operations. Scanning the code on iPhone itself is not complicated, but sometimes it will be easy to adjust it slightly when encountering special circumstances.
