| Abstract: | The paper takes STM32F103VET6 as core, compliant with ISO / IEC 15693 standard portable reader with RF chip CR95HF. At the same time, it uses wireless storage chip M24LR64 to develop a new type of passive RFID tag matching the reader. This RFID system works at frequency 13.56MHz, the capacity of tag reaches 24 KB, and it can realize data transmission with I^2C bus interface, suitable for carrying large amounts of data on the label applications. The Results prove that the developed RFID system works stably in wireless data transmission, and it has the features of stable working status and broad applicable range. |
