If this app from Wildcard Network works the way it claims, it may solve a problem I’ve always had with gift cards, not having them with me when I am at a store and want to use them. The app allows you to virtually store your gift cards in the iPhone so that you can use them at any time. You can even check balances right from the app. The app is free.

What is the downside? Very few supported cards right now. For instance, I have in my wallet two Barnes & Noble gift cards and a Home Depot gift cards. Neither of them is supported at this time. They also don’t support open-loop (Visa/MasterCard) gift cards (yet?). If they are able to widen their support to most gift cards, this could be a very cool app.
