What is dot technology and how it works?
I have to go to a special pen and paper and pencil, look close and had plenty black dots on it and had a flight pen sensor that is detected. Also, I am an engineer and I know how these things are. Please no answers like: "I do not know what you talking about" or "what is fly pen" or something similar.
You find some good information on this site: https://www.anoto.com/digital-pen-paper.aspx basically dot pattern on paper is not uniform, is unique in the entire site, and even one piece of paper, on the other. The pen has a digital camera that sees what you write, as well as a dot pattern. Since the dot pattern is unique, that can always tell where the paper it is. May then such information used to interpret what you write.
