I do agree that QR codes can be used for trolling, but there's absolutely no reason you can't inspect the URL before visiting a link from a QR code - all that's stored in the QR code, after all, is the URL!

- gerggerg 15y agoIt's phishing. Sure, you're going to check the url. But most people won't. And simply being on the bank is going to be validation enough for most.
