Frequently Asked Questions

Here, you’ll learn everything about QR Codes and how to scan them.

What is a QR Code?

A QR code is a type of machine-readable encrypted code similar to bar codes. Each QR code is square-shaped and is made up of a unique arrangement of smaller black and white squares. These codes can be scanned using a QR code scanner. They contain data in the form of text and can be used to show phone numbers, email addresses, URLs, etc.

Here is an example of a QR code.

You can download this code and scan it using our tool to give it a try. (Don’t worry though! It only contains a URL to this same page.) 

Can I scan a QR code from a picture?

Yes, you can scan a QR code from a picture. You can directly scan the picture using your device camera or upload the image to the QR code scanner from your local storage. 

How to scan a QR code on the same phone screen?

You can scan a QR code on the same phone screen by taking a screenshot of it and uploading it to an online QR code scanner tool.

What Should I Do If the QR Code Is Not Working?

There are a few reasons why the QR code may not work. Here are some solutions that you can try:

• Make sure that the QR code is clear and visible and is not low quality. Sometimes, the code can become blurry, making it difficult to be scanned.
• Make sure that your device’s camera is clean (if you are scanning in real-time). Any dirt or grime on the camera can negatively affect the scanning process.
• If you are checking a QR code that you’ve created yourself, make sure that you added the data properly, such as a URL, phone number, or plain text.
• If you are scanning the QR code using the camera, make sure that the full square is aligned inside the frame.
• Also, ensure that there is proper lighting (if you’re scanning the code) so that the code can get properly scanned.

Can a QR code be hacked?

The QR Code itself is static and has no inherent vulnerabilities that can be exploited. However, the content embedded within a QR code can potentially lead to security risks. For example, a QR code could direct users to a malicious website that attempts to hack and steal sensitive information. This is known as a QR code phishing attack.

To minimize the risks associated with QR codes, it's crucial to practice good security habits when scanning them:

• Verify the source: Only scan QR codes from trusted sources or entities you trust.
• Use a reliable scanner: Ensure you use a reputable QR code scanner, as some third-party websites/apps may have security vulnerabilities.
• Pay attention to the destination: Before scanning a QR code, take note of the URL or content it will direct you to. If it seems suspicious or unfamiliar, avoid accessing it.
• Keep your device updated: Regularly update your device's operating system and security patches to help protect against potential vulnerabilities.
