With its compact, low-profile footprint, this scanner/scale is ideal for space-constrained checkouts and seated cashier environments. The NCR RealPOS Low Profile Bi-Optic Scanner/Scale incorporates NCR"s Optical Effects Technology (OFX), featuring a cutting-edge design that drives more scan lines at greater lengths to dramatically improve performance. The resulting dense pattern of scan lines captures and reads even difficult-to-read barcodes, including those that are small and truncated. To make it even easier to use, the cashier interface offers a customizable scan adviser using five brightly color-controlled LEDs, which communicate scanner status and successful scans. This scanner/scale includes many features designed to make it easier to service and provide greater configuration flexibility. This protects your investment and reduces total cost of ownership. Serviceability enhancements include three independent service zones that require only five screws (of the same type) to service the entire scanner.
