Designing the Pass

Before a pass can be sent to any users, the pass needs to be designed and configured. The pass provider needs to determine what type of pass should be used and how the pass should look. This includes figuring out what fields of information should be presented on the pass, where the fields should be placed, whether a barcode should be used, and what information will be provided to determine whether the pass should be displayed on the lock screen. An individual pass is actually a signed bundle of files, including some images, a JSON file called pass.json with information about the pass and display information, and a signature and manifest.
