RFID communication systems are increasing drastically in recent days, but main drawbacks of present systems limiting the customer needs. The main feature should have by the communication system is security. Maximum present systems are providing security but whereas communication is not error prone hence security also went back foot, more over waiting time of tokens is more because of serial accessing, all the problems can de-addressed by our proposed method. In our proposed method parallel two stage operation called pre and post stages are introduces hence waiting time can be reduced. CRC error checking can be used for the error determination.
