Hi everyone, I'm excited to announce the release of our first iPhone application, CardStar. CardStar is a club card / reward card / membership card manager. We have a built in merchant list of over 100 companies to make card entry as easy as possible: just select the merchant and enter your membership number. CardStar will generate a barcode to match the one on the back of your card. Most merchants can scan your card from your iPhone screen (which is very cool, for you and the cashier), but if that doesn't work, it's still a handy place to keep your membership number to enter manually. It's 0.99 and available now at the iTunes store. Thanks!
