Today, Square unveiled its latest attempt to put the traditional cash register out of business. Square Stand, which is currently available for pre-order for $299, features an integrated card reader for processing payments. An iPad will connect to the built in stand and the POS software will run on iOS. The stand is engineered so you can connect to receipt printers, barcode scanners, a cash register and anything else needed to deliver a full point of sale experience. Square Stand will be available this July online and at retailers such as Best Buy.
