The IBM SurePOS™ 500 series point of sale is retail hardened for the harsh environment of food service but is being used in other markets because of its all-in-one form factor and small footprint. This unique touch-screen system never requires recalibration, avoiding costly downtime and reducing input errors. Advanced technology, including a brighter, high-contrast screen, with adjustable touch sensitivity, helps speed transactions by improving cashier accuracy and performance. The easy to use touch-screen also reduces employee training time. The displays are completely sealed to avoid damage from liquids and contaminants.
