Ah, the old piggy bank. It was a great way to learn how to save your pennies when you were a kid, and there was always that satisfying smash to look forward to when you had finally saved up enough to buy that skateboard or whatever other high-priced item you wanted more than anything else in the world. As adults, we don't really need such items anymore. But that's not stopping high-minded designers from trying.

The Credit Card Piggy bank is a concept that allows you to save money by inserting a credit card in and having it wirelessly connect to your bank. It can also be used as a donation center, essentially just acting as a public credit card reader for places where you'd want to give money. Of course, there are already plenty of card readers out there that aren't shaped like pigs. Somehow, I don't think this'll be catching on, but hey, you never know.
