This handheld POS device can pay by scanning code, swiping card, or NFC payment function. It subverts the traditional small screen using a 5.5-inch high-definition touchscreen. This makes the human-computer interaction more friendly and user operation more convenient. The fuselage is designed to have a light and thin structure, and the grip is designed with gradient anti-skid texture, which is more conducive to grasping, and achieves the best state of ergonomics.
