- kube-system 4y agoAs far as technology is concerned, QR codes are far less advanced or secure than EMV. The only thing it compares favorably (and I’m being generous) to in terms of payment security is magstripes, which is a 1960s technology. QR codes have basically no inherent security. They are just barcodes in two dimensions. You can do physical MITM attacks on them very easily.

- cuteboy19 4y agoWhy so? QR is just an arbitrary url in image form. If anything EMV is both overcomplicated AND insecure. Eg the whole class of vulnerabilities from card theft and card skimming disappears with QRs Edit: I mean you could have a computer screen display the QR. How are you going to MITM between the screen and your phone?
- kube-system 4y agoNot all QR codes in Asia are on a phone. QR codes are inherently graphical, and anything printed can be simply covered up or replaced. Smart cards at least can at least implement public/private keys.
