Abstract :
This paper presents a 13.56 MHz RFID reader that can be used as a door-lock for home security. The RFID reader consists of a transmitter, a receiver, and a data processing block. To verify the operation of the developed RFID reader, we present both a PSPICE simulation for transmitter/receiver and a digital simulation for data processing block. In particular, a CRC block for error detection of received data and a Manchester decoding block for position detection of collided data are designed using VHDL. In addition, we applied a binary search algorithm to multi-tag anti-collision. The anti-collision procedure is carried out by PIC microcontroller on software. Both the experimental and simulation results show that the developed reader can provide the right multi-tag recognition
