The SAM4S NR-520F is a strong, heavy-duty electronic cash register built for busy food and drink businesses like bars, cafes, and fast-food restaurants. It comes with a special flat, splash-proof keyboard that protects the buttons from accidental spills and lets you program up to 60 items for fast, one-touch selling. It also features 2 built-in printers, meaning it can print a receipt for your customer and save a physical paper copy for your business records at the exact same time. With a clear 8-line display screen and a full-size metal cash drawer, this machine makes checkout fast, safe, and simple.
