A wireless pairing system includes an emitting terminal and a receiving terminal, the emitting terminal includes an emitting terminal storage unit, a traversal unit, a pairing unit and an emitting terminal wireless transceiver. The receiving terminal includes a receiving terminal storage unit, a detecting unit, a coupling receiver and a receiving terminal wireless transceiver. The emitting terminal transmits matching requests in priority to receiving terminals having been paired in history record. The receiving terminal in priority gets the matching request sent by the emitting terminal having been paired with at last time, thereby pairing cycles can be effectively shortened, and pairing efficiency of the mitting terminal and the receiving terminal can be effectively improved.
