The ubiquitous QR code, that pixelated square of information, has become an integral part of our daily lives. From contactless payments to accessing websites and downloading apps, these codes offer a convenient and efficient way to interact with the digital world. But what happens when the QR code you need to scan is displayed on your iPhone’s very own screen? Fear not, tech enthusiasts! This comprehensive guide will walk you through various methods and troubleshooting tips to seamlessly scan QR codes displayed directly on your iPhone screen.
Understanding the Challenge: Scanning a QR Code on the Same Device
Scanning a QR code that’s displayed on your own device presents a unique challenge. Traditionally, QR code scanning involves using a camera on one device to capture the image of a QR code displayed on another surface – a poster, a product, or even another screen. When the QR code is on your iPhone’s screen, the built-in camera is essentially trying to scan its own display, which isn’t a typical use case. This requires a slightly different approach, bypassing the usual camera-based scanning process. The iPhone offers several clever workarounds to overcome this hurdle, empowering you to access the information embedded within the QR code effortlessly.
Method 1: Leveraging the Screenshot Method and the Photos App
One of the simplest and most reliable ways to scan a QR code displayed on your iPhone screen is to use the built-in screenshot functionality in conjunction with the Photos app.
Taking a Screenshot of the QR Code
First, you need to capture the QR code as an image. This is achieved by taking a screenshot. The method varies slightly depending on your iPhone model:
- iPhones with Face ID (iPhone X and later): Simultaneously press and release the Side button (power button) and the Volume Up button.
- iPhones with a Home button (iPhone 8 and earlier): Simultaneously press and release the Side button (power button) and the Home button.
You’ll see a brief flash on the screen and hear a camera shutter sound (if your sound is enabled), indicating that the screenshot has been successfully captured. The screenshot will be saved directly to your Photos app.
Scanning the Screenshot within the Photos App
Once you have the screenshot, navigate to your Photos app and locate the image containing the QR code. Open the image.
Now, here comes the magic. iOS intelligently recognizes QR codes within images. Simply tap and hold on the QR code within the screenshot. A contextual menu will appear, offering options related to the QR code’s content.
If the QR code contains a website URL, the menu will display an option to “Open in Safari” or “Copy Link.” If it’s a contact card, you’ll see options to “Create New Contact” or “Add to Existing Contact.” Choose the appropriate option based on the QR code’s function.
If tapping and holding doesn’t work immediately, ensure that Live Text is enabled. This feature allows your iPhone to recognize text and other information within images. To enable Live Text:
- Go to Settings > General.
- Tap on Language & Region.
- Make sure Live Text is toggled on.
With Live Text enabled, your iPhone should readily detect and offer options for interacting with the QR code within the screenshot.
Method 2: Utilizing Third-Party QR Code Scanner Apps
While the built-in screenshot method is effective, dedicated QR code scanner apps offer another convenient alternative. Numerous QR code scanner apps are available on the App Store, many of which are free and offer additional features.
Choosing a QR Code Scanner App
When selecting a QR code scanner app, consider factors such as:
- Reviews and Ratings: Check the app’s ratings and reviews on the App Store to gauge its reliability and user satisfaction.
- Features: Some apps offer additional features like history tracking, custom actions, and the ability to create your own QR codes.
- Privacy: Ensure the app respects your privacy and doesn’t request unnecessary permissions.
Popular and reputable QR code scanner apps include:
- QR Code Reader by Scan: A widely used app with a clean interface and reliable scanning capabilities.
- QR Code & Barcode Scanner: Another popular option with a range of features, including barcode scanning.
- Kaspersky QR Scanner: An app focused on security, warning you about potentially malicious QR codes.
Scanning the QR Code Using the App
Once you’ve downloaded and installed a QR code scanner app, the process is straightforward.
- Launch the QR code scanner app.
- Most apps will automatically activate the camera. However, some might require you to tap a button to initiate scanning.
- Instead of pointing the camera at a physical QR code, look for an option to “Import from Photo Library” or “Scan from Image.” This option allows you to select the screenshot you took of the QR code.
- The app will then process the image and decode the QR code, presenting you with the relevant information or action options.
Method 3: Using Siri Shortcuts for Advanced Automation
For users seeking a more streamlined and automated solution, Siri Shortcuts offer a powerful way to scan QR codes on your iPhone screen. Siri Shortcuts allows you to create custom workflows that can perform a series of actions with a single tap or voice command.
Creating a Siri Shortcut for QR Code Scanning
- Open the Shortcuts app on your iPhone (if you don’t have it, download it from the App Store).
- Tap the “+” icon in the top right corner to create a new shortcut.
- Tap “Add Action.”
- In the search bar, type “Scan QR Code” and select the “Scan QR Code” action.
- Now, add another action by tapping “Add Action” again.
- Search for “Show Result” and select the “Show Result” action. This will display the decoded QR code content.
- Tap the three dots in the top right corner to name your shortcut. Give it a descriptive name like “Scan Screen QR Code.”
- You can also customize the icon and color of the shortcut for easy recognition.
- Tap “Done” to save your shortcut.
Using the Siri Shortcut
To use the shortcut, simply tap its icon in the Shortcuts app. The shortcut will automatically access your camera, but since you need to scan a QR code from your screen, you’ll need to adapt the process slightly.
- Take a screenshot of the QR code.
- When you run the shortcut, it will attempt to use the camera. Ignore this.
- Instead, use a third-party app (like “Barcode Scanner”) to scan the QR code from the screenshot.
- Once scanned by the third-party app, copy the result.
- Now, run your Siri Shortcut. It will ask for input since it can’t directly scan the screen.
- Paste the copied result into the input field and the Shortcut will display the result.
While this method requires an extra step using a third-party app to initially decode the image, the Siri Shortcut streamlines the final presentation of the result, making it a more efficient process overall, especially if you frequently need to scan QR codes from your screen. This method isn’t fully automated but offers a faster way to present a copied QR code result.
Troubleshooting Common Issues
Even with these methods, you might encounter some issues while trying to scan a QR code on your iPhone screen. Here are some common problems and their solutions:
- QR Code Not Recognized: Ensure the entire QR code is visible in the screenshot and that it’s not blurry. Try adjusting the brightness of your screen or zooming in on the QR code before taking the screenshot. Also, verify that Live Text is enabled in Settings.
- No Options Appearing When Tapping and Holding: This usually indicates that Live Text is disabled or that the QR code isn’t being recognized as a valid QR code. Double-check the QR code’s integrity and try a different scanning app.
- App Asks for Camera Permission: When using a QR code scanner app, it will require camera access. However, you’re not using the camera directly to scan your screen. Look for the “Import from Photo Library” or similar option within the app.
- QR Code Leads to a Suspicious Website: Always exercise caution when scanning QR codes, especially from unknown sources. Verify the website URL before visiting it and be wary of phishing attempts.
- Shortcut Not Working: Double-check the steps in creating the Siri Shortcut and ensure all actions are correctly configured. Consider testing the shortcut with a simple QR code (like one linking to a well-known website) to isolate the problem.
By understanding these troubleshooting tips, you can overcome common obstacles and successfully scan QR codes displayed on your iPhone screen with ease.
The Future of QR Code Scanning
QR codes are likely to remain a prevalent technology for the foreseeable future. As technology evolves, we can anticipate even more seamless and intuitive ways to interact with these codes.

The ongoing advancements in image recognition and artificial intelligence will undoubtedly enhance the accuracy and speed of QR code scanning, making it an even more integral part of our digital interactions.
How do I scan a QR code that’s already on my iPhone screen?
Unfortunately, the native Camera app on your iPhone can’t scan QR codes displayed on the same device’s screen. It’s designed to scan codes presented externally, using the phone’s camera to interpret the visual information from another source. The camera needs an external view of the QR code to process it, which is impossible when the QR code is an image on the same screen.
To scan a QR code shown on your iPhone screen, you’ll need to use a workaround. The simplest solution is to take a screenshot of the QR code and then use a QR code scanner app that allows you to upload images from your photo library for scanning. Many free QR code scanner apps are available in the App Store that offer this functionality, effectively circumventing the limitation of the native camera app.
What is the best QR code scanner app for iPhone to scan screenshots?
Several QR code scanner apps in the App Store excel at scanning QR codes from screenshots. A highly recommended option is “QR Reader by Scan.” This app is known for its user-friendly interface, fast scanning speeds, and reliable performance.

Another excellent choice is “QR & Barcode Scanner” by Gamma Play. This app supports a wide range of barcode and QR code types and is known for its accurate scanning capabilities. It’s also free and has a clean, intuitive design, making it easy to navigate and use for scanning QR codes from screenshots saved in your iPhone’s Photos app.
Can I use Siri to scan a QR code on my screen?
No, Siri, Apple’s virtual assistant, does not have a built-in functionality to directly scan QR codes displayed on your iPhone screen. Siri primarily interacts with apps and system features through voice commands, and there’s no existing command to initiate a scan of an on-screen QR code. Siri relies on other apps to perform actions, but cannot directly process the visual information of a QR code displayed internally.
However, you can potentially use Siri Shortcuts to create a custom command that automates the process of taking a screenshot and then opening that screenshot in a QR code scanner app. This would require setting up a Shortcut that captures the screen, saves the image, and then opens it in a compatible app like “QR Reader by Scan” or “QR & Barcode Scanner.” This method provides an indirect way to use voice control with scanning QR codes on your screen.
Are there privacy concerns when using third-party QR code scanner apps?
Yes, there are potential privacy concerns to be aware of when using third-party QR code scanner apps. Like any app, these scanners may request permissions to access your camera, photo library, or location. It’s crucial to review these permissions carefully before granting them. Some apps might collect and share your data, including scanning history or location data, for advertising or other purposes.
To mitigate these risks, choose reputable QR code scanner apps with a proven track record of protecting user privacy. Read the app’s privacy policy to understand how your data is collected, used, and shared. Also, consider disabling unnecessary permissions to limit the app’s access to your personal information. Regularly check app permissions and updates to ensure your privacy settings are maintained.
How do I take a screenshot on my iPhone to capture the QR code?
The method for taking a screenshot on your iPhone depends on the model you have. For iPhones with Face ID (iPhone X and later), press and hold the side button (power button) and the volume up button simultaneously. Quickly release both buttons, and the screen will flash, indicating a screenshot has been taken. The screenshot will be saved to your Photos app.
For iPhones with a Home button (iPhone 8 and earlier), press and hold the side button (power button) and the Home button simultaneously. Release both buttons quickly, and the screen will flash to confirm the screenshot. This screenshot will also be saved to your Photos app, ready to be used by a QR code scanner app that accepts image uploads.
What if the QR code is too small on my screen to scan effectively?
If the QR code is too small to scan effectively, try zooming in on the QR code before taking a screenshot. Pinch to zoom in within the app or website displaying the QR code to make it larger and more legible for the scanner. A larger QR code image will provide more detailed information for the QR code scanner app to analyze, increasing the likelihood of a successful scan.
Alternatively, if the QR code is an image, you can try saving the image to your Photos app and then using the built-in photo editor to crop the image tightly around the QR code. Cropping away unnecessary surrounding content will further enlarge the QR code within the image and help improve scanning accuracy. Some QR scanner apps also offer built-in cropping tools.
Can I use the Google Lens app on my iPhone to scan a QR code on the screen?
Yes, the Google Lens app, available for free on the App Store, offers a convenient way to scan QR codes displayed on your iPhone screen. Unlike the native Camera app, Google Lens allows you to upload images from your photo library for analysis. After taking a screenshot of the QR code, open Google Lens, select the image from your photos, and the app will automatically detect and decode the QR code.
The Google Lens app is particularly useful because it can also perform other functions, such as identifying objects in images, translating text, and providing information about landmarks. Using Google Lens provides a versatile solution for scanning QR codes on your screen without needing a dedicated QR code scanner app, adding extra functionality beyond simple QR code decoding.
