Exactly so contactless payments in general for you guys is a completely new concept. Therefore there is a lot of confusion around the whole contactless payments thing. Had you been using contactless without apple pay for a while consumers and retail staff would be more familiar and issues with Apple Pay would occur less.
So I guess Im trying to say that its not Apple Pay that people are having problems with, its actually contactless payment technology and the terminals already deployed which don't sound like they are fully optimised for NFC. Which is absolutely not Apple's fault.
