Other than the software, what other equipment will I need to purchase?

At a very minimum, you'll need a computer with a standard keyboard, mouse and monitor. (Remember, the Orion POS software requires a Microsoft Windows compatible computer.) Most POS registers using the Orion POS also have a standard 40-column receipt printer, a scanner to read barcodes, a cash drawer to store cash and various tenders, and a pole display to let the customers view and verify the item prices and transaction total.
