Since it won't be until towards the end of the year when it is released my hope is that the Apple Pay team will be trying to settle deals with banks to implement it for when it's released with iOS 11, or shortly afterwards. Most banks over here now have the option to pay your friends and family directly from the app and free of charge, hopefully they see Apple Pay as just an easier way of implementing simple bank transfers. The more automation available to them will over time require them to have less staff at branches, possibly less branches, and certainly less staff to employ for telephone banking, so they should hopefully just see it as an extension of the services they offer.
