Notes: The ISBN scanner feature requires a device with an auto-focus camera (e.g. iPhone 3GS or newer, iPad 3 or newer) for native camera support. If you have a fixed-focus device (e.g. iPad 2) we use a companion app for scanning that will be seamless to you. We will walk you through it when you launch the scanner.
