The League

A collegue of mine has developed a website for our internal company tabletennis league that is based on the elo rating system. His website uses socketIO and ist quite nice to use. But for myself and some other guys it was a little bit difficult to remember all set values if we played in our free time.

The Idea

So an idea came to my mind that we have a battery pwoered device at the table tennis field to send the points directly to the server. The fact that each of us has his own rfid tag at the keyring just made it clear to use them as an identification token for the player.
