The reading portion has a square shape with sharp corners on the front side, and the periphery gradually widens in all directions toward the back side, with rounded corners that gradually increase in radius when viewed from the front, giving it a trapezoidal shape when viewed from the side. A camera is installed on the front of the device, and an ambient light sensor is installed to the side of the camera. A small speaker hole is installed on the bottom of the device. As shown in the [Reference Diagram Showing the Usage State], this device is installed so that the reading portion is exposed on the wall of a building entrance or other area equipped with an automatic locking / unlocking door.
