A wireless scoring machine for epee and foil fencing is used to generate and receive radio signals transmitted through a traditional epee or foil for counting scores and displaying the scores, wherein the tip of the blade of an epee or a foil equipped with a conductive element electrically is connected to a radio transmitter box. When the tip is in contact with a body of a fencer, the conductive element and the body form a closed circuit to transmit electric power to actuate a radio transmitter to transmit radio signals followed by a radio receiver base station receiving the radio signals and continuously generating electric current to actuate a relay to enable a calculator to calculate the scores followed by displaying the scores.
