Re: I'm puzzled by these attempts.
"The difference between this and the other types of payment service is that the merchant does not see your card details. Thus they can't track your shopping habits! For the likes of Tesco this is not good. I will very surprised if they sign up for apple Pay at launch."
Yes I'm even more surprised they accept that "Cash" thing, I mean that doesn't even have a unique WiFi / Bluetooth signal that can be tracked around the store.
