1. Physical Warning Signs

* Sticker edges, bubbles, or a code that sits slightly higher than the surrounding print. * A code on a surface where one would not expect it, such as a meter that has no payment sticker elsewhere. * Different print quality compared with the rest of the sign.

2. Check the Link Before Opening

Most camera apps show the destination URL before opening. Read the domain carefully. Look for misspellings, extra words, unusual endings, or a shortener that hides the real target.

3. Behavior Red Flags

* Requests for passwords, card details, or one-time codes. * Urgent threats or prizes. * Prompts to install an app from outside the official store.

4. If In Doubt

Type the official web address yourself or use the organization's app instead of the code.

Frequently Asked Questions

Can I tell a malicious QR code just by looking at it?

No. The symbol looks the same either way. Judge the destination URL and the context.

What should I do if I opened a suspicious link?

Close it, do not enter details, and change passwords if you did. Report it to the organization concerned.
