I have a friend with an iPhone and he has the app CardStar. For anyone who hasn't seen this, you type all your "preferred customer" cards (Jewel, Dominicks, Blockbuster, Best Buy Rewards, gym membership, etc) into the phone and it stores them for access later. When you need the card, you just choose it and it displays the barcode on the phone screen which can be scanned right on the screen. This saves a lot of time and unclutters your keychains. It would be great if there was a Windows Mobile alternative. They mention they are working on blackberry and android alternatives, but no WM.
Anyone know of a similar program?
