QR Code Security: How to Stay Safe When Scanning
Are QR codes safe? Learn about 'Quishing,' how to identify malicious codes, and why privacy-first generators are essential.
As QR codes become more popular, security has become a major topic of discussion. While the QR code itself is just a piece of data, the destination it leads to can sometimes be harmful. Understanding QR security is essential for both creators and scanners.
What is 'Quishing'?
Quishing, or QR Phishing, occurs when a bad actor replaces a legitimate QR code with a malicious one. For example, a scammer might stick a fake QR code over a parking meter's official code to steal credit card information.
How to Identify a Malicious QR Code
- **Check for Stickers:** If you are scanning a code in a public place, check if it is a sticker placed over an original design.
- **Preview the URL:** Most modern smartphone cameras show a preview of the link before you click it. If the URL looks strange or uses a suspicious domain, do not open it.
- **Avoid Shortened Links:** Be wary of codes that lead to unknown URL shorteners, as these are often used to hide the final destination.
Why 'Static' Codes are Safer
At FreeQR, we specialize in static QR codes. Unlike dynamic codes, which redirect you through a third-party server, static codes can be 'read' directly. If you encode 'https://google.com' into a static code, that is exactly where the scanner goes, with no middleman involved.
How FreeQR Protects Your Privacy
Most QR generators require you to create an account and store your data on their servers. This creates a data privacy risk. FreeQR uses client-side generation, meaning:
1. **No Data Collection:** Your passwords and links stay in your browser.
2. **No Tracking:** We don't track who scans your code or where they are located.
3. **No Account Required:** You don't have to give us your email address to use our professional tools.
Tips for Creators
If you are a business owner, you can protect your customers by:
- **Using High-Quality Printing:** This makes it harder for someone to overlay a fake sticker without it being obvious.
- **Verifying Your Links:** Regularly scan your own displayed codes to ensure they still lead to the correct, secure location.
- **Educating Your Users:** Include your website URL in plain text below the QR code so users know where they are going.
