Starbucks has updated their iPhone app to support Passbook. With the Starbucks app, you can manage your Starbucks Card balance, reload your card and track your Stars in the My Starbucks Rewards program. With it’s latest update, more people may start using Apple’s new Passbook app. Passbook is designed to get users directly into gift cards or event tickets from the lock screen when they are near a Starbucks or other area that supports Passbook.

The Starbucks app can be downloaded for free in the App Store via this link. However it doesn’t support the iPhone 5 screen yet.
