Square Coupons

Square is a mobile payments company based in San Francisco, California, that acts as a merchant account provider to allow participating sellers to accept credit and debit cards online, on the telephone, or during face-to-face sales. Participating merchants can swipe debit and credit cards on an iOS or Android smartphone or tablet computer using a small plastic device that is inserted into the audio jack of the device. The company also offers their more robust Square Stand equipment that turns an Apple iPad into a complete point-of-sale device, so that retailers can use it instead of a traditional cash register and credit card reader.
