Due to some safety requirements, the POS machine can only be designed with upper and lower shells as a whole, and the internal overall device package must be installed in the upper shell. In terms of materials, it is also mainly plastic. The design direction can only be designed through face plate modeling, hand-held feeling and some plug-in ports as design points.

This is a small M-POS machine for personal use. The overall design highlights the business sense in color matching. It uses a large feature and uses bright and dumb surface contrast to make it run through the overall contour shape.

Taking the plug-in port as the breakthrough point of modeling design, it spreads to all sides. Considering the hand-held feeling of the product, some surface changes have been made at the side to enrich the details.
