Choose a Reliable QR Code Reader App
The first step is to install a trusted QR code reader app from the Google Play Store. There are many options to choose from, but here are some top recommendations:
- Google Lens – This increasingly popular AI-powered app from Google has excellent QR scanning capabilities. As a bonus, it can provide additional information about landmarks, products, text, and more.
This app is installed by default on your phone. Just search it on your app search bar.
- QR Code Reader – With over 100 million installs, this aptly named app quickly and easily scans QR codes without unnecessary bells and whistles.
- Kaspersky QR Scanner – The security experts at Kaspersky provide a fast, safe QR code scanner. It checks links for malicious content before opening.
- Barcode Scanner – From ZXing Team, this open-source app has been a go-to option for reliably scanning QR codes for years.
Look for apps that have solid ratings and reviews. It’s ideal to choose an established app from a reputable developer rather than some new or unknown option. For security, avoid apps that ask for unnecessary device permissions.
Open the App and Allow Camera Access
Once you’ve installed your preferred QR code scanning app, open it and allow access when prompted so that it can utilize your device’s camera.
Here are the steps for granting camera permissions:
- When opening the app for the first time, you will get a pop-up asking if you want to allow access to the camera. Select Allow.
- If you accidentally denied access previously, go to Settings > Apps & Notifications (maybe under Apps or Application Manager on some devices).
- Select the app and tap Permissions.
- Turn on the Camera permission.
Enabling camera access allows the app to instantly scan codes through the viewfinder. Without it, the app won’t function.
Align the QR Code Within the Viewfinder
Now comes the actual scanning part! Follow these tips for successfully scanning a QR code:
Step 1: Open the QR scanner app and point your device’s camera at the QR code, keeping about 6-12 inches away.
Center the code squarely within the viewfinder area. Try not to cut off any edges.
Step 2: Hold the camera steady. Shaky movements can throw off the scanning.
Step 3: For improved focus and scanning, tap the screen where the QR code is located.
Step 4: The app will automatically scan the code once a clear image is detected.
Step 5: If the code doesn’t scan immediately, slowly move the camera closer or further away until it’s recognized.
Good lighting is important. Avoid scanning codes in low light when possible.
Step 6: For damaged or hard-to-scan codes, try capturing the image with the camera, then tapping the preview to scan.
Step 7: If the code contains a web link, select the notification that pops up to open it. For other code types, follow the prompts.
For IOS devices:
Scanning with IOS devices is easier than with Android devices. Here is how to do it
Step 1: Open the camera app on your IOS device.
Step 2: You just need to hold the camera in front of the QR code from a certain distance and focus the camera on the QR code.
Step 3: After you have focused on the QR Code, there will be a QR code pop-up sign. Tap on it.
Step 4: After tapping on it, the QR code will take you to the designated link, and you are done.
And that’s all there is to it! With a reliable app and allowing camera permissions, scanning QR codes on Android devices is quick and painless.
