Projector
A projector comprising a main body, a radio frequency identification (RFID) tag and a controller is provided. The main body comprises a light module and an optical engine. The light module is used for emitting a light. The optical engine is used for receiving the light and outputting a projecting image. The RFID tag is coupled to the main body and is used for providing an identification data to recognize the identity of the projector or a user. The controller reads the identification data from the radio frequency identification tag or writes the identification data to the radio frequency identification tag by a communication interface.
