How to Safeguard Your Privacy While Scanning QR Codes



QR codes have become integral to our digital lives, providing quick access to information, services, and interactive experiences. Though QR codes continue to gain popularity, it is essential to be mindful of our privacy and security while scanning them. In this article, we will explore practical steps to safeguard your privacy when interacting with QR codes, ensuring you can enjoy the convenience they offer without compromising your personal information.

Choose a Reliable QR Code Scanner App:

The first step in protecting your privacy is to select a trusted QR code scanner app. Stick to reputable options available in official app stores. Look for scanners that prioritize user privacy, have positive reviews, and offer built-in security features. Research the app’s privacy policy to understand how it handles and stores your data. Avoid scanners that request unnecessary permissions or seem suspicious.

Be Cautious with Third-Party QR Code Scanners:

While many smartphones have built-in QR code scanning capabilities, you might come across third-party scanners that claim additional features or benefits. ExpressVPN’s study shows that exercise caution when using such apps, as they may collect and misuse your data. Stick to the default scanner on your device or opt for well-known and trusted third-party options.

Inspect the QR Code and Source:

Before scanning a QR code, take a moment to inspect its design and the context in which you encounter it. Ensure the code appears genuine, without signs of tampering or modifications. Pay attention to where you find the code—be wary of randomly placed stickers or codes in suspicious locations. Verify the source of the QR code, ensuring it comes from a trusted and reputable entity.

Use Device Features to Preview URLs:

One way to protect your privacy is to use your device’s features to preview the URL behind the QR code. Before scanning, long-press the QR code or hover your cursor over it to reveal the destination URL. Check if the URL matches the expected context, and be cautious of any unexpected or suspicious domains. If in doubt, refrain from scanning the code to avoid potential privacy risks.

Beware of QR Codes in Untrusted Environments:

Exercise caution when scanning QR codes in untrusted environments or from unknown sources. Public spaces, advertisements, or unsolicited emails or messages may contain QR codes that lead to malicious websites or collect your personal data. Be particularly vigilant when encountering QR codes that promise prizes, discounts, or freebies, as they could be attempts to gather your information.

Disable Auto-Execution of QR Codes:

Some QR code scanning apps have a feature that automatically executes the action associated with the code, such as opening a URL or initiating a payment. While convenient, this feature can be a potential privacy risk. Disable auto-execution in your QR code scanning app’s settings to gain more control over the actions performed when scanning a code. This way, you can review and decide whether to proceed with the intended action.

Stay Updated and Secure:

Keeping your smartphone and apps updated is crucial for maintaining your privacy and security. Regularly install updates for your device’s operating system, QR code scanning app, and other relevant applications. Updates frequently incorporate security patches that effectively target vulnerabilities and fortify defenses against emerging threats.

Review App Permissions:

When installing a QR code scanning app or any other application, carefully review the permissions it requests. Be cautious if an app asks for excessive permissions unrelated to its functionality. Grant only the necessary permissions to protect your privacy and limit the access apps have to your personal data.

Educate Yourself About QR Code Security:

Stay informed about the latest security practices and trends related to QR codes. Keep yourself updated on common QR code scams, phishing techniques, and privacy risks associated with scanning QR codes. By educating yourself, you can better identify potential threats and make informed decisions while scanning QR codes.

Be Mindful of Personal Information:

Exercise caution when QR codes require you to provide personal information. Question the necessity of sharing certain details and consider the potential risks involved. Legitimate organizations typically follow strict privacy guidelines, but it’s important to remain vigilant and avoid sharing sensitive information unless you trust the source explicitly.

Trust Your Intuition:

Lastly, trust your instincts. If a QR code or the context in which it appears feels suspicious or too good to be true, it’s better to err on the side of caution and avoid scanning it. Your privacy and security should always take precedence, and it’s better to miss out on an offer or promotion than to compromise your personal information.


QR codes have become integral to our daily lives, offering convenience and quick access to information. However, it’s crucial to prioritize privacy and security while scanning QR codes. By choosing trusted scanning apps, inspecting QR codes and their sources, previewing URLs, being cautious in untrusted environments, disabling auto-execution, staying updated, reviewing app permissions, using privacy mode or VPNs, and educating yourself, you can safeguard your privacy and enjoy the benefits of QR codes without compromising your personal information. Maintaining your privacy is a continuous effort, so stay vigilant and adopt these best practices to protect yourself in the evolving digital landscape.
