The SAM4S NR-510F is a high-performance electronic cash register built specifically for the food and hospitality sector, including cafes, bars, takeaways, and food trucks. It features a splash-proof 90-key flat keyboard and a single-station thermal printer. Unlike twin-station models, it operates on a single printer roll to save counter space and reduce paper waste, relying on a massive internal memory to save and print business audit logs on demand.
