The Bottom Line
Are QR Codes Safe?
The QR code itself is not dangerous.
A QR code is simply a way of storing information that a smartphone can read.
The security risk comes from the destination behind the QR code.
For example:
A QR code can link to:
โ A legitimate website โ A product page โ A payment page
But it could also link to:
โ A fake website โ A phishing page โ Malicious content
The QR code is simply the doorway.
The destination determines whether the experience is safe.

- Payment information
- Personal information

Attackers may use stolen information for:
- Fraud

- Account access
