I have been using Square for several years now and for the most part very happy with it. Had problems with the first chip reader I got but they replaced it very fast at no charge if you get the old one back to them in a certain amount of time. The chip reader needs to be charged up every day. You can find the regular readers at just about any retail store now. I have even seen them in Home Depot. I know that when I was able to start accepting credit/debit cards my sales went up quite a bit! Good luck on the sales!
