Design and Implementation of RFID Controller using Verilog HDL

Manual monitoring consumes more time, man power and shows inaccurate results. So, automation is the solution to cover the problems stated. Barcode and RFID are two different forms of automated technology that are used for reading and collecting data. The RFID (Radio Frequency Identification) technology is a well-known wireless application for traceability, logistics and access control. The RFID controller is constructed in to demonstrate access control through the use of low-frequency RFID tags. These tags contain identification number which is read by the reader, sent to a database where it is compared with stored values. It works on the principle that If the tag’s identification number is in the system database, it gives access. If the data is not in the system database, it doesn’t give access. To implement these various blocks, include RFID transmitter, RFID receiver, Baud clock generator, Database are designed. The RFID Controller is designed using Verilog HDL in Xilinx ISE tool.
