There is a new Product right now called the Square and it is being marketed by the founder of Twitter, Jack Dorsey.
Basically, this device is the size of a postage stamp(its really small) and it connects right to your Iphone, Ipad, Ipod Touch, or Droid Phone and allows you the average guy/gal to accept credit card payments for anything you are selling or for a home business.
