Puts another nail in the "it's just a consumer toy" argument.

Fantastic idea and implementation, is this the start of the end of windows check outs?

Wow. Wiping out the old-fashioned POS (Point of Sale) cash machine with iPad. I like it.

Aren't regular, old fashioned cash registers very expensive?

This looks like a nice product. 

This is an incredible value. Well done.

This is a brilliant product.

You can get an unconnected traditional cash register from Costco pretty cheap:  http://www.costco.com/CatalogSearch?storeId=10301&catalogId=10701&langId=-1&keyword=cash+register

But the Square system you can play Angry Birds while waiting for a customer. :D

I really hope someone comes up with a full business in a box-- integrate a NAS with wifi and VPN, and modular apps for things like inventory, services, payroll... that isn't an over-priced cloud solution. One-man consulting/service businesses are a great target, but many other small businesses make sense too.

This could work really well for kiosk operators.

$300 for the drawer / stand / Square

$400 for the IPad 

$300 for a printer 

===============

$1,000

As opposed to other systems that network and cost much more.

Or cost less and include more. E.g.

I don't know if the Square swipe fee is reasonable, but I suspect that can be had for less, too.

I wonder how this handles checks. It'd be nice if you could verify and submit the check for cashing immediately like I can with my banking App.

If only Square would pull their finger out and release over in Europe/UK.

However, Visa have locked everything down as we use PIN codes and not signatures so they demand different technology, not just a card swiper.
