Description

Electronic Circuit schematic like in Figure 1 above is Electronic Circuit Schematic RFID Based Access Control System using AT89S51. According Circuitstoday site that An RFID based Door Lock or Access Control System is based on some simple concepts. We store a set of RFID card data in our system, say 3 or 10 RFID card data. When the person with the right RFID card (compatible to data preloaded in our program/system) come and swipes his RFID tag, access will be granted. When the person with the wrong RFID card (whose data is not loaded in our system) swipes his RFID tag, access will be denied. I hope you understand the system concept of RFID based Door Lock.
