You may have encountered a poster or flier with a QR code and decided to simply snap a picture of it to view later. Now that you have time to look at it, you want to access the information on the code, but aren't sure if you can from a picture in your camera roll. Can you scan a code from a picture you’ve already taken? The answer is yes!
In this piece I will go over the simple steps and requirements to scan a QR code from a photo so that you can access the information provided within it. Let’s get started!
Methods to Scan a QR Code from a Photo
Most smartphones today have built-in QR code scanners. Scanning QR codes using built-in scanners is typically the easiest way.
Here's how to scan a code using an iPhone or Android device.
Method 1: Using Built-in Phone Scanner
For iPhone (iOS 15 & later):
- Save the QR Code Photo in your photos gallery or take a screenshot.
- Go to photos, tap the QR Code image, and view it on the screen.
- IOS will directly recognize it and display a notification with a link or information if it is clear and visible.
Troubleshooting - If the link isn't displayed, try zooming in on the image and ensure it is well-lit.
For Android (Google Lens):
- Save the QR Code Image in your device's gallery.
- Open Google Photos or Google Lens.
- Scan the QR Code - Activate the scanning feature, and Google Lens will automatically display the link or information.
Troubleshooting - Ensure that the image is clear and well-positioned if the QR Code doesn't get detected. Google Photos provides you with a cropping tool that can enable you to focus on the QR Code.
Method 2: QR Code Scanner Apps
If, for any reason, you cannot use the built-in feature, there are many QR code scanning apps you can use.
- Pick any QR scanner app from PlayStore or AppStore and download it. Allow the App to access your camera and photo gallery.
- Upload the Photo - Look for an option that says "Scan from Gallery," "Import Photo," or "Upload Image."
- Once you upload the photo the App will automatically analyze the photo and scan it.
Method 3: Using Online QR Code Scanners:
Online QR Codes are a good option when you don't want to download an app and want to get the information directly from the browser.
- Simply search for a QR code scanner and choose one from the results.
- Upload the QR Code Photo. Look for an option like "Upload Image" or "Browse" to access the QR Code image stored in your smartphone.
- The QR Code will then be automatically scanned.
Common Security Risks to Avoid
While scanning a QR code it is important that you make sure both the QR code and the scanner (if it's not in-built) are safe to use. Scams are at their all-time high globally, so it’s important to be careful and take extra precautions.
For example, various QR Codes were placed in a parking lot in America, and when drivers scanned these codes, they were redirected to fraudulent websites that charged exorbitant parking fees. While QR codes are relatively safe, they do come with some dangers and you should treat them with the same level of scepticism as you would any URL address or link you may find online.
Conclusion
Scanning QR codes couldn’t be easier. Whether you use your phone's built-in scanner or an app, the process is quick and straightforward. Remember to prioritize security, use trustworthy scanners, and use your best judgment when dealing with codes. With these methods, you can quickly access information from any QR code image.
