Hip to be Square

I was always intimidated by taking credit cards. It was going to cost too much money- I don't do shows every month so how can I handle the fees, overall it would be too scary for my small business. Then I met the square.
Changed my world and perspective! It is a simple ap to use and it automatically transfers the funds into my accounts the next business day. I've used it at all of my shows this summer and (knock on wood) haven't had an issue yet! I wish I would have taken the plunge earlier. If you are a small business I HIGHLY recommend this new partner :)
How about you? Do you use the square? Maybe another equally awesome piece of technology?
