Whenever we wanted to save up money in the past, we would put all of our change and spare dollars into a piggy bank. Now that the whole world is going to electronic and plastic, it seems that we don�t have cash in hand to put back.

Thankfully, a few people out there know this and have created a concept for the modern piggy bank that will accept plastic. It�s a cross between the classic piggy bank and Tamagotchi. There�s a little character that lives inside, and will want you to �feed it� every now and then. It uses your iPhone as a computer to keep track, but will harass you to put in your credit card when it wants to be fed. Once happily full, it will doze off into peaceful slumber till yet again hunger calls. This might be a little annoying, but it will help you to put a little money back here and there. Though it is a neat way to save money, it�s likely going to be a little expensive as well.
