Somewhere, a flight is sold-out at a busy airport and to stay on schedule the passengers must board quickly. The check-out line is growing at a popular boutique and the customers are not happy. An engineer struggles to add direct part marking into his space-constrained product design. The Motorola DS457 Series can help, delivering fast, high-volume hands-free scanning of virtually any bar code — including 1D, 2D and direct part marks. No matter what type of bar code is presented, or whether it is printed on paper, etched into a product or displayed on a mobile phone screen, the DS457 Series provides fast, accurate scanning in a tiny footprint that fits in the most space-constrained areas.
