The present disclosure provides an identifying device, an identifying system and a method for identification between a transmitting wireless apparatus and a receiving wireless apparatus, wherein the transmitting wireless apparatus senses a plurality of wireless apparatuses to provide sense information, calculate relative location information between the transmitting wireless apparatus and the wireless apparatuses based on the sense information and convert the relative location information into an identification datum. The transmitting wireless apparatus transmits a broadcast message having the identification datum. When the receiving wireless apparatus receives the broadcast message from the transmitting wireless apparatus, the identification information of the broadcast message is compared with sense information sensed by the receiving wireless apparatus. When the error value between the identification information and the sense information sensed by the receiving wireless apparatus is less than a permissible value, the receiving wireless apparatus is determined as an object receiving the broadcast message.
