There are many ways to transmit data between the device and the device. For example, when a teacher presents a slide on the podium, we can use a mobile phone camera to take a picture, however, the image data obtained by this method may not be clear. In addition, it is not convenient to copy the data to the teacher after class. Contemporary information sharing methods include technologies like cameras reading QR codes, but these are not helpful for tra
