What does with those below thread then? You said you've use search engine, but you can't use search engine to find old discussion about QR code scam, how shame it is.

1. {Warning}: Fake Bitcoin QR Code Generators
2. [Warning] Bitcoin QR code maker
3. QR Code replacement scam
4. [Alert! Alert] Bitcoin QR Generator” lead to scam websites.

Due to my skepticism I never use any QR code when it comes to exchanges or wallet, it's better to copy-paste the address and triple check it.
