1. The document presents an RFID-based access control system project. It includes an overview of the system's introduction, block diagram, tools and resources used, concepts, circuit diagram, working, video demonstration, applications, advantages, and disadvantages. 2. The system uses an RFID reader to identify users by scanning their RFID tags. If the tag ID matches one stored in the microcontroller's memory, access is granted. Otherwise, access is denied. 3. The project aims to automate access control for security purposes and unauthorized access prevention through contactless identification of users.

- 10. 10 RFIDBASEDACCESSCONTROL SYSTEM PROJECT PRESENTATION:2012 Concept used : 8051 Microcontroller: •A 8051 microcontroller have 4 ports and each ports Having 8 pins. •It is 40 pins IC •4k ROM(on chip program Space in bytes) •128 bytes RAM •2 Timers •32 I/O pins •1 serial ports •6 Interrupts sources
- 11. 11 RFIDBASEDACCESSCONTROL SYSTEM PROJECT PRESENTATION:2012 RS232: •To allow compatibility among data communication equipment. •It is in DB 25 and DB 9. •It is most widely used in serial I/O Interfacing standard. •The I/O are not TTL compatible, In RS232 1 is represented by -3 to-25v ,While a 0 bit is +3 to +25v ,making -3 to +3 undefined we must use a voltage converter such ac MAX232.
- 12. 12 RFIDBASEDACCESSCONTROL SYSTEM PROJECT PRESENTATION:2012 MAX232 IC: •It is 14 pin IC. • A line driver such as the MAX232 chip is required to convert RS232 voltage levels to TTL levels, and vice versa •8051 has two pins that are used specifically for transferring and receiving data serially. •These two pins are called TxD and RxD and are part of the port 3 group (P3.0 and P3.1). •These pins are TTL compatible; therefore, they require a line driver to make themRS232 compatible.
- 13. 13 RFIDBASEDACCESSCONTROL SYSTEM PROJECT PRESENTATION:2012 L293D: •It is 16 pin IC. •The L293D device is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL & TTL logic levels & drive inductive loads(such as relays solenoids, DC and stepping motors) and switching power transistors. •It is use as a motor driver.
- 14. 14 RFIDBASEDACCESSCONTROL SYSTEM PROJECT PRESENTATION:2012 LCD: •It able to display numbers characters, and graphics. •It has 14 pin
- 16. 16 RFIDBASEDACCESSCONTROL SYSTEM PROJECT PRESENTATION:2012 Working : • Low frequency RFID works on the principle of radio waves and at the frequency of 125 KHz. • There is a coil inside the RFID tag and when it is influenced by magnetic field, it sends an identity code to a device for further processing. •The RFID tag is used as an identity for a particular user. If the identity (serial number of the tag) of the user is matched with the one already stored in this system, he gets immediate access through it. •In beginning, the user is prompted to scan his tag or ID. The serial code of the tag is identified by the reader module and is sent to AT89C51 for checking.
- 17. 17 RFIDBASEDACCESSCONTROL SYSTEM PROJECT PRESENTATION:2012 •If the ID is matched by the microcontroller, the user gets the access. On the contrary, if the tag is not identified, a message (‘Access Denied’) is displayed on LCD screen.
- 19. 19 RFIDBASEDACCESSCONTROL SYSTEM PROJECT PRESENTATION:2012 Application: •Security Purpose •Unauthorized Access Control •Automated database updation
- 20. 20 RFIDBASEDACCESSCONTROL SYSTEM PROJECT PRESENTATION:2012 Advantages: •An RFID smart card-based system may reduce operation costs in the long run. •RFID equipment damage occurs much less frequently than is the case with magnetic strips or bar codes present on Charlie Tickets.
- 21. 21 RFIDBASEDACCESSCONTROL SYSTEM PROJECT PRESENTATION:2012 Disadvantage: •In the short run, costs of diffusion and implementation for an RFID access control system is more. •Poor read rate can occur if the reader and receiver are not properly aligned.
