SAN FRANCISCO – Mobile payments start-up Square has its sights on reinventing the cash register, USA Today reports, with its new Square Stand that transforms an iPad tablet into a digital point-of-sale system.

"Hardware makes software better," said Square co-founder Jack Dorsey. "Customers of merchants (using Stand) never have to think about payments.

The $299 Square Stand works with Square Register, the mobile app that turns an Apple iOS or Google Android device into a mobile payment system.

Square Stand features a built-in card reader and connects to receipt printers and bar-code scanners. It is compatible with second- and third-generation iPads.

The stand is available through Square’s website and will be sold at Best Buy stores beginning in July. 

Square said it processes more than $15 billion mobile payments each year, with half of its processed payments coming from iPad users.

Cash registers are "not the sexiest thing" in the world, Dorsey says. "More important than how (Stand) looks is how it works."
