QPS-213, a portable scanner weighing only 390 g, enables users to easily scan A4-sized documents, photos, negatives and filmstrips to save them digitally. Unlike a traditional scanner that needs a computer, it works independently with USB stick or SD card for data input and output. A touch on the power key initiates it instantly to complete the task, easy for everyone to operate, including those unfamiliar with computer-related tasks. It uses lithium battery, so it can work without power cable and can be charged via USB connection. The geometric composition, the design’s core, highlights the document feeding zone and button, facilitating intuitive usage.
