I got a new phone from AT&T and this app was preinstalled on it. I signed up for an account but I'm apprehensive about adding cards to it.
I've seen how in Europe they can intercept your card info. This seems to beam your card info from the back of your phone. How safe do y'all think it is?
And also, does swiping have to be physical to get your rewards or would this still count as swiping?
Thanks!
