In the mobile radio-frequency identification system, the accuracy and rapidity of tag recognition are undergoing great challenges. In this article, we proposed a novel tag anti-collision identification method based on tags’ priority called RPA in the mobile radio-frequency identification system. The algorithm sets the priority of recognition according to the sequence of tag entering the recognition area. The reader does not recognize the tags with low priority until the ones with high priority have been identified totally. The experimental results show that when the tags’ moving speed is lower than 4 m/s, the system can identify the total tags without loss, and the efficiency and identification speed can reach 73.7% and 762 tags per unit, respectively.
