Abstract

It is disclosed that a mobile scanner includes only the minimum components to operate as a scanner. The disclosed scanner does not have a separate power supply to energize the components to work. Further, unlike many scanners in the market, there is not a single microcontroller in the disclosed mobile scanner while the performance thereof could outperform those scanners commanded traditionally by a microcontroller in the scanners. The disclosed scanner is coupled by an interface engine to a computing device that provides system control signals and power supply. The interface engine comprises a control circuit providing logic control signals to the scanner to operate in response to the system control signals. As such, the scanner is of high performance and low cost and so lightweight that it can be used in any conditions.
