- Payment: PayNow, PayLah!, or other payment details.
- Authentication: Two-factor authentication codes or login tokens.
Why Decode QR Codes?
Before scanning a QR code with your phone, it's wise to decode it first to check what it contains. This helps you identify potentially malicious links, verify Wi-Fi credentials, or simply understand what data you're about to share with an app.
Security Risks of QR Codes
While QR codes are convenient, they can pose security risks if not handled carefully:
- Malicious URLs: QR codes can hide phishing links or malware download pages. Always verify URLs before opening.
- Data Harvesting: Some QR codes may link to sites that collect your personal information without your knowledge.
- QR Code Swapping: Attackers may replace legitimate QR codes (e.g., parking payment codes) with malicious ones.
- Privacy Leaks: Sensitive information in QR codes (like Wi-Fi passwords or contact details) could be exposed if shared carelessly.
How to Stay Safe:
- Always decode QR codes from unknown sources before opening links
- Verify the URL matches the expected destination
- Be cautious with QR codes in public places
- Don't share screenshots of QR codes containing sensitive data
- Use this decoder to preview content safely before taking action
