In order to complete the reader with anti-collision algorithm based on power control, a design of power progra-mmable UHF RFID reader is proposed, which narrates the operational principle of the reader in details and introduces the specific design of the system. The operating frequency band of the reader is 840-960 MHz. It can complete reading and writing tags. In particular, through MCU to control the output power of power amplifier, the reader can realize the anti-collision algorithm based on power control, which improves the anti-collision performance, and also cuts down the energy consumption in great extent.
