It's mobile payments with NfC. Been doing it for a few years. Looks like it will work the same way.

I work at Target... I still deal each shift with people that don't trust us and only pay cash, that don't trust us so they don't use their Red Card anymore, but swipe something else, and then there is the lady that used to work in a bank fraud department 20 years ago that only writes a check.... heaven help you if you get her on a "bad" day. Overall she is nice, but the lectures each trip are rough.
wel target was hacked. I dont trust them either
