The detection and identification of the chessmen is performed by a so called RFID technology (Radio Frequency Identification). Each chessman contains a tiny microchip, which provides a unique ID, to the board. This technology is not only very accurate and reliable, but also extremly power saving.
Hence the board does not require any external power supply, and is fully satisfied by the supply from the chess-clock, which can provide power for several hundred hours of broadcasting.
The technology provides chessman position accuracy on a milimeter scale. A full board scan will take less than 0.15 sec depending upon the number of chessmen on the board.
