Membership and rewards cards stuffing my wallet have always been a problem for me. In the old days (before iPhone) you could help the problem by printing the bar codes on a single card and using that one card in the stores. Now as the smart phones have become so much more intelligent, there is an even more elegant solution.
Please enjoy CardStar, an iPhone application that lets you enter all your membership and rewards cards into your phone and display them at checkout when you need them! I don’t have an iPhone to try it but judging by the screen shots I already love this little app. I wish there was something similar in Android Marketplace so I could use it on my G1.
By the way, the app is currently free (regular price is $0.99).
