UberPOS is a point-of-sales system built on top of the Drupal and Ubercart. It provides an AJAX interface for cashiers to easily add products to a customer's order, as well as remove them, accept payment, cancel entire orders and print receipts.
The current install and included addon modules allow UberPOS to be used with touch screens, mice, and programmable keyboards, barcode scanners, receipt and other printers, and credit card readers. New October 2010: Support for multiple locations has been added. Many thanks to ICA Projects for their sponsorship of this functionality.
