Leave those bulky plastic "reward cards" and "club cards" at home! CardStar lets you easily store, manage and quickly retrieve your reward, club, and loyalty cards on your smart phone, where they can be scanned directly from your screen at most merchants.
This iPhone app has reduced the size of my wallet by 50%. I now have all my grocery and discount cards on my iPod Touch, available within a few clicks. It supposedly will allow the displayed barcodes to be scanned but I have not been successful with that so far. The clerks usually have to key in the code....still worth not carrying all those cards around.
I read on CardStar's site that screen protection may be the culprit in my inability to scan. Additionally, they say that handscanners work better than the flatbeds used at registers. I am going to keep trying but I love this app even without that ability. Go on, give it a try yourself...it's free on iTunes here
