Square Debuts its Latest Hardware, a $299 Card Swiper for iPad Registers

So what happens with signatures? I recently visited a cafe where they were using an iPad as a checkout, and the cashier had to constantly swivel the thing around to let customers sign for their purchase.<p>I know it's not that big an inconvenience, but it just seemed like an awkward conclusion to a transaction that's supposed to be simplified by these devices.

Here in Barcelona we're using wireless for paying. Each card has a chip you just get your card close to the read and bam, you payed the bill. It's nice and confortable.

Is there any chance that Square (or any of its competitors) will open up their service to custom app developers?<p>I want to build a custom application that uses their hardware and payment processing back end. But I can't.

Are there any wires needed to hook into receipt printers, cash boxes, etc?

This is great. Their hardware has always been one of the weak points in the experience - people hate swiping on the wobbly headphone-jack doohickeys. Having something much more solid would help.

Honestly I'm a little surprised it took this long. Seems like a no-brainer for the company.

But does it accept Bitcoin?

And firearms/firearm accessories stores around the world shrugged.
