Square - accept credit card payments on your Smart Phone

This is very cool. Use your Smart phone to accept credit card payments. According to the website there are no contracts, monthly fees, or hidden costs. They claim you can effortlessly manage all the money you take with an easy and intuitive interface. I like the sounds of that. You can't sign up just yet (but we will when you can) - but you can find out more at Squareup.com
