Hi, sorry for late reply. Actually, the author sent me wrong files in the zip archive for "RFID based attendance system". I have updated the zip file on the server and now you can download again.

So you can see the new circuit for RFID based attendance system, there A is used, which is a off-page connector label. that means, its connected to label A mentioned on the second circuit diagram, i.e. the A of pin 10 of 89S52 is connected with pin 6 of RFID reader.

Please do not confuse yourself with 8051 architecture and 89s52 IC. please tell me if you want to know anything more..
