These are instructions on how to enable and use Passbook in the iOS 6 beta.
In order to use the Passbook you must add a pass; otherwise, you'll only see a generic welcome screen.
Step One Using your device, navigate to http://www.passsource.com, a site that was created by Kudit to help generate passes.
Tap to select a pass you would like to generate.
Step Two Input the details required for the pass. Note: Some pass types will let you fully customize the pass with everything from location to barcode to color.
Press the Create button once you've entered all the pass information.
Step Three The pass will then be opened in Passbook. Press the Add button at the top right to add the pass to your Passbook.
Step Four You can now open Passbook from the Springboard to view your passes.
It does work on Beta 2 but requires a slight workaround.
1. Install iUnarchive Lite from the App Store
2. Use PassSource.com as normal to generate a pass. When the pass is displayed onscreen, Open In "iUnarchive Lite"
3. Say "No" to unpacking the archive
4. Click the Sharing icon and select "Email file" and send it to yourself
5. Open "Mail" and view the email you just sent to yourself.
6. Click the "Card" attachment and then "Add"
This also works for passes you have updated through PassSource.com
No need to thank me.
