QR codes can also be a tool for scams or fraud if you're not careful. Hackers can create QR codes that lead to suspicious websites or download malware onto your device. To stay safe, follow these tips:

1. Avoid scanning unknown QR codes, especially in untrusted or suspicious places.


2. Verify the source before scanning the code.


3. Use reliable QR code reader apps, as some have features to warn you about malicious links.


4. Never share personal or financial information after scanning a QR code unless you're certain of the source.

Being cautious can help protect your data and keep you safe.
