Tip: Ask staff if you're unsure about the QR code's authenticity. Legitimate restaurants will be happy to verify.
Payment QR Codes
Always double-check payment QR codes, especially in public places. Verify the amount and recipient before completing the transaction. Scammers often replace legitimate payment codes with their own.
Tip: Use payment apps with built-in security features that verify merchant information.
Public Wi-Fi
Be cautious when scanning QR codes for Wi-Fi access. Verify they're from the legitimate network provider. Fake Wi-Fi QR codes can lead to man-in-the-middle attacks.
Tip: Use a VPN when connecting to public Wi-Fi to encrypt your connection and protect your data.
