CardStar

Those member rewards cards on your keychain're great, but misplace your keys, and you're left wandering the mean streets without access to shelter or 15% off Olay Regenerist moisturizer. Letting you keep the benefits while losing the bulky plastic: CardStar

Just now dropping the Android and Blackberry versions of its popular free iPhone app, DC-based CardStar allows you to store all manner of rewards/club/whatever cards in a single virtual location, de-cluttering your keyring/wallet/lanyard that proves you definitely attended lacrosse camp in 1998. It's all ludicrously easy: to add cards, select the desired merchant from a menu of over 500 pre-listed establishments and enter your account number (generally right below the barcode); next time you need it, just pick the merchant to bring up the barcode, which you can hold right up to the scanner, all of which'd totally impress the clerk at checkout, if their soul hadn't died long, long ago. Merchants're divided into 20 categories, including frequent flier programs, gyms (Bally's to the YMCA), all kinds of big-name retail (Ace Hardware to Vitamin Shoppe), library cards, and "services" like Apple ProCare, FedEx, and something called "Massage Envy", which presumably involves unresolved (deep) tissues

In the coming weeks and months, Star'll also be rolling out user-specific "deals", which'll offer perks (free tastings at liquor stores, savings on Gillette razors, etc) at specific merchants based on info about what kinds of cards you hold and how often you use them -- which will be frequently, considering how Proactiv you are.
