S2 is a POS scale based on the Android system. It provides a solution for weighing, billing and receipt printing. Unlike the bulky and somber image of conventional POS scales, S2 has a sense of modern style and technology. It also features several user-friendly details: the corners of the base are diagonally sliced off to expose the level screw, making it easier to adjust for installation and reducing the heavy appearance of the base. The edges of the weighing pan are slightly bent upwards, preventing goods falling from the pan. An orange color embellishment outlines the gap between the pan and the base, hence the entire base appears thinner and lighter.
