Symbol’s rugged DS3478-SF 2D cordless digital bar code scanners use digital imaging technology to accurately capture all types of one-dimensional (1D) and two-dimensional (2D) bar codes while offering the high performance typically found only in laser scanners. With the DS3478-SF from Symbol, the user benefits from a scanning solution designed specifically for fast-paced production environments. Symbol's DS3478-SF cordless 2D scanner comes equipped with charge coupled device (CCD) image sensors, which allow them to more accurately capture and process bar codes at a faster pace than other digital scanners. In addition, Symbol's DS3478-SF scanner’s omni-directional scanning functionality lets operators quickly capture bar codes from any angle, eliminating the need to line up bar codes with laser lines. The DS3478-SF from Symbol has the widest working range of any scanner in its class. Its two-position smart focus technology, unique to Symbol, allows the user to read bar codes regardless of the size or density of the code. This means this single device works well for all scanning needs.
