RFID based Secured access system using 8051 microcontroller (AT89C51)

[reshi]

Hi….I am referring to the project "RFID based Secured access system using 8051 microcontroller (AT89C51)" by Himanshu Chaudhary. I want to know what Rfid module has been used. I have rfid rc522 and EM-18 but no one seems working. Moreover, in the circuit diagram of the same project, only pin no. 5 and 2 of the module have been used while as i think three pins are needed at least-Vcc,Gnd and Tx. So, i need  to know it urently what special module is this and what pin is connected to what??

Thank You
