Intuit's GoPayment card reader available in its 2,300 retail stores. The small business-friendly machine plugs into a BlackBerry, Android or iOS device to transform the smartphone or tablet into a credit card processing machine using a free app. After a $30 mail-in rebate, the hardware is free with no monthly fees and a 2.7-percent fee per transaction. Merchants who upgrade to the premium version for $12.95 per month will only have to fork over 1.7-percent fee per swipe, bringing the net income on that dollar tube of processed meat to just over 98 cents. Plus, Intuit is throwing in two months gratis for the paid version. Check out the full PR after the break, and don't forget the ketchup and mustard.
