Apple, which launched the "EasyPay" system of allowing users to buy accessories and self-checkout at Apple Stores by scanning a bar code with the Apple Store app on their iOS device late last year, plans to add Passbook functionality that could allow users to buy (and eventually even reload) Apple Store gift cards, possibly book Genius Bar appointments or provide reservations on top-selling items, or allow users to buy more expensive hardware and other items using Passbook's pay codes.
