References to new iPad models with Touch ID support and a settings page for Apple Pay have been discovered hidden in the just-released beta of iOS 8.1. Developer Hamza Sood posted the evidence on Twitter this evening, in the form of three screenshot images.
The first two images, which you can see above, show a new Passbook pane in the Settings app for setting up Apple Pay, as well as a Privacy Policy page for the new mobile payment service. In the page, Apple outlines what user data it collects, and what it does with it.
