Question 1

Can a QR code be dangerous?

Accepted Answer

Yes. A QR code can open a fake banking site, install an iOS configuration profile that decrypts all your encrypted traffic, add a hostile eSIM that takes over your phone number, or dial a code that wipes your phone. You cannot tell any of this by looking at the code.

Question 2

What is quishing?

Accepted Answer

Quishing is phishing delivered by QR code. It grew from 0.8% of all phishing in 2021 to around 12% in 2025, because a QR code hides its destination until it is too late to read it, and moves the victim onto a phone where warning signs are harder to see.

Question 3

Does QR SafeCode send my scans to a server?

Accepted Answer

No. Scanning and security analysis run entirely on your device. The content of a code you scan is never transmitted. When a code is judged dangerous the app does not contact that server at all, so an attacker never receives your IP address and never learns their code was scanned.

Question 4

How do I know if a QR code sticker is fake?

Accepted Answer

Criminals paste their own sticker over a legitimate QR code on parking meters, chargers and restaurant tables. Scan with QR SafeCode first: it decodes the destination without opening it and tells you if the domain is imitating a known brand, hiding behind a shortener or disguising an IP address.
