What is CardStar you say? Its a very cool little app that lets you store all of your "convenience cards" in one place. Instead of having loads of cards or keytags for the video store, gym, car rental agencies, pet store, library, hotels or supermarkets, you just need the CardStar app on your mobile device. You simply enter your card information, and the bardcode can be displayed right on the screen. No more carting around loads of plastic cards that get lost and worn out. There are loads of retailers in the CardStar database, and you can submit a request for addional retailers if yours isn't listed in the system.

The CardStar app is listed as coming soon, and a tweet by @mycardstard yesterday stated the app will be hitting BlackBerry on May 1st. Definitely something to look forward to. I know I'm excited to ditch all those worn out tags on my keychain in favor of this app. For more details, hit up Thanks to Ben for sending this in!
