CardStar Lets You Keep Your Points Cards in your iPhone… And Check-In To FourSquare

CardStar is an interesting iPhone application that allows users to consolidate all their various reward cards, club cards and such into one application. The premise is that you’d walk into a store, open up the CardStar application, and the clerk can literally scan your phone to find your rewards account. Taking this to a new level, the latest release of CardStar now integrates with Foursquare, allowing users to check in while they use their loyalty card at a given store.
