And I thought it was pretty good...
back in the UK for a few months and picked up an iPhone 6 to use whilst here...it noticed when I was setting it up that my Wells Fargo cards were supported and promptly added them to the iPay thing. Worked flawlessly at Boots, Sainsburys and Greggs (all in Reading). The interface was neat, and it let me choose between my debit and credit cards. I must admit the various till staff thought I was a bit odd until it flashed up on their screens that I had pid. I think my only complaint at this point is the £20 maximum.
