How to spot a fake or tampered QR code
Scammers sometimes stick their own codes over real ones on parking meters, posters and menus. A fake code opens a copy of a real page to steal your details.
A few habits protect you.
How do I tell if a QR code has been tampered with?
Look for a sticker placed over the original code, uneven edges or a code in an odd place. Compare it with the other codes around it.
What should I check after scanning?
Read the address your phone shows before opening it. If it looks wrong, misspelled or unrelated, do not open it.
- Never enter a password or card number on a page you reached by an unexpected code.
- Type the real web address yourself if unsure.
Which codes are higher risk?
Codes asking for payment, a login or an app install, especially in public places. Be cautious with parking and payment stickers.
