See full text

An optical identification device includes a circuit board, a top cover, an optical detection module and an optical channel. The top cover is disposed on the circuit board and has an identification region. The optical detection module is disposed on the circuit board and located inside the top cover. The optical detection module includes an optical emitter and an optical receiver. The optical emitter is adapted to emit an illumination beam toward the top cover. The optical receiver is adapted to receive the illumination beam reflected from the top cover. The optical channel is disposed between the optical emitter and the top cover, and adapted to block the illumination beam from projecting onto a lower surface of the identification region facing the optical receiver.
