Clicked Paper Billboard
You may build multiple receivers into a paper billboard (behind the paper).
The light beam of our pointers can simply pass several layers of paper.
Since you know the position where you have placed them, you can tell the Advertisement Agencies
where to place graphical interaction points on the paper.
It is a good idea to wire the message receivers for power supply in this specific case because a lot of people might
click the billboard while passing with the car.
The message data is sent to the transceiver station and processed just like we explained before but we
propose to use a low cost GSM/3G/4G/5G module to forward the data to your office
or directly to our PointerNet.
