point of sale

I asked about Ubercart and POS integration at tonight's Meetup at Duke Corporate Education. One short Google later and here's what I found:

http://uberpos.com/

From the front page of the site:

uberPOS is an open source point-of-sales system built on top of the Drupal Content Management System (CMS).

With uberPOS you can:

Easily and quickly add and remove products with a scan gun
Set up membership discounts
Accept cash, checks, credit cards
Print customizable receipts
Give refunds
Customize the interface for your shop
...and more
