How to scan QR codes safely
QR codes are on menus, parking meters, tickets and posters, and they are convenient precisely because you cannot see where they lead. That is also why scammers use them, for example by sticking a fake code over a genuine one. A few habits keep scanning quick and safe.
Safe scanning habits, then QR code scanner apps. If you entered card or login details after scanning a suspicious code, contact your bank or change the password straight away.
Use a trusted scanner
Phone cameras can read QR codes directly. If you prefer an app, choose one from a known developer that shows the content before acting on it.
Read the link first
Look at the address before you tap. Misspelled brand names, odd domains and shortened links on payment pages are warning signs. When in doubt, type the official website yourself.
Inspect codes in public places
On parking meters, charging stations and posters, check for a sticker placed over the original code. Use the official app of the operator for payments when you can.
Know what a code can do
A QR code can open a link, join a Wi-Fi network, add a contact or start a payment. Confirm what it is about to do before accepting. Compare apps in QR code scanner apps; for securing accounts, see how to set up two-factor authentication.
