Please note:
- This is not a real Passbook Pass
- It is an image containing a Passbook Barcode of your message encoded by the PassKit API
- Use this image, like you would a real Pass, to prepare for integration of Passbook into your business
- Unlike a Passbook Pass this image will rotate and the screen saver could activate
