Passbook is a new feature coming to iOS 6 that will give users something of a virtual wallet within their iPhone.
Users who are running iOS 6 (you must be registered as a developer with Apple) can use the software already. It was never quite clear how to go about it, but some instructions have made their way to the internet.
Here’s how to use it, according to 9to5Mac:
1) Open PassSource.com on your iOS 6 device.
2) Select which type of pass you would like to create.
3) Fill in the pass with the necessary information, such as card number and member name.
4) Hit ‘Create’
5) It will then open inside the Passbook app, and you are ready to go.
