What Are QR Codes and How Do They Work?

QR codes (Quick Response codes) are two-dimensional barcodes that can store information and are easily scanned using a smartphone camera. They can direct users to websites, download apps, or provide contact details. While convenient, QR codes can also be manipulated by cybercriminals to redirect users to malicious websites or download harmful software.

How to Stay Safe While Scanning QR Codes?

To stay safe while scanning QR codes, follow these guidelines:

1. Verify the Source: Only scan QR codes from trusted sources. Avoid codes from unknown or suspicious locations.
2. Use a QR Code Scanner App: Some apps provide security features that can detect malicious links before opening them.
3. Check the URL: After scanning, check the URL carefully before proceeding. Look for HTTPS in the URL, which indicates a secure connection.
4. Avoid Scanning Codes in Public Places: Be cautious with QR codes found in public places, as they can be easily tampered with.
5. Update Your Device: Keep your smartphone’s operating system and apps updated to protect against vulnerabilities.
