QR codes can be used safely with a few practical precautions.
Always scan codes from trustworthy sources, such as verified
businesses or known individuals. Before proceeding, visually
inspect the QR code to ensure it hasn’t been tampered with,
like stickers placed over legitimate codes.
Use your smartphone's built-in camera app rather than
unfamiliar third-party apps, and preview the link before
opening it. Avoid scanning random codes in public places or
from unsolicited messages-if in doubt, type the address
manually into your browser instead.
Never enter sensitive details such as passwords or payment
information unless you are confident the site is legitimate
and secure. Keep your device's software updated, enable
security features, and regularly check for official
communications or privacy policies when scanning codes for
access or payments. By following these steps, you can enjoy
the convenience of QR codes while minimizing risks.
