Summary:RFID is a popular automatic identification technology currently, which large opportunities. Active RFID system has more advantages in long distance applications than passive RFID system, but it is also in face of the collision problem when many cards work together. On the basis of comparing today's mainly used anti-collision algorithms, an improved anti-collision algorithm (DCMA) is proposed for the active RFID in this paper. The algorithm is designed and simulated, and finally tested in an active RFID hardware platform. The simulation shows the low power advantage of the DCMA algorithm in the active RFID system
