QR codes are powerful, but power comes with responsibility. Here's how to keep your codes secure and your users safe.
Password Protection
When creating a QR code, you can enable password protection. Visitors must enter an access code before viewing the content. This is essential for internal documents, private event details, employee resources, and exclusive offers.
Dynamic Code Security
Since all codes on PerfectQRCode are dynamic, you have a security advantage: if a code is compromised or misused, you can instantly deactivate it from your dashboard. No waiting for printed materials to expire — one click and the code stops working.
How PerfectQRCode Protects Your Data
All connections use HTTPS encryption. Passwords are securely hashed with ASP.NET Identity. Uploaded files undergo magic byte validation (we check the actual file content, not just the extension). Security headers protect against XSS, clickjacking, and MIME sniffing. Directory traversal attacks are blocked with path validation. Read our full Privacy Policy for details.
For QR Code Scanners
Most phones preview the URL before opening it. Check the domain — does it look legitimate? Be cautious of QR codes in unexpected locations, especially stickers placed over original codes (a common tampering technique). When in doubt, don't scan.
