Abstract：The design scheme of a low-power portable RFID reader is proposed. The design idea, hardware structure and software design method of RFID reader are given in details. The RFID reader based on MSP430 series of ultra-low power microcontroller to control, it combined with nRF2401 RF chip and real-time clock chip PCF8563, read and write tags to achieve real-time recording. The reader has a high practicality and reliability, low cost, low power consumption， and has a good application prospect.
