A New Approach for RFID Tag Data Reading in FPGA by using UART and FIFO

Nowadays, Radio Frequency Identification (RFID) technology used for automatic object tracking and identifying purpose. RFID technology used in so many applications especially in automobiles, security and health care systems. RFID reader and RFID tags are main processing units in RFID system. RFID tags give the information on what an object is, where it is and even its condition, and what is happening, share related data and respond to the reader. RFID reader module used for reading data from lots of RFID tags. In convention methods [1][2] doesn’t contain any read controller methodology and doesn’t contain any storage element for RFID tags data storing. In this paper, we propose a new approach for RFID tag data reading in FPGA. This approach is more flexible in structure and easily updates the design for any applications. This design is easily adaptable for different chips and communication mechanism. This design has reading controlling methodology and along with storing capability of RFID tags by using FIFO. Here we are using Universal Asynchronous Receiver and Transmitter protocol for communicating RFID reader to PC. For simulation, we are using ModelSim software and for synthesis, purpose using XILINX ISE 14.7.
