The project describes working of a system implemented in a library, which facilitates book issue and return based on RFID code attached to books. It uses microcontroller to control gates.

3. INTRODUCTION
• Developing a smart logic for automatically detect the USER which has to be issued
with the help of RFID and automatic deduction of tariff for book issue.
• tag to every user. This unique number is store in the silicon chip and placed in the
identity card of every student and teacher. No one can change this code.
• This UID code is already store in the data base of library system. When any person
carrying a book, reach near the exit gate then the Rf passive card reader generate a 125
kHz frequency for decoding RF tag.
• If the data base is ok then person is asked to enter his password. If everything is
correct and account has sufficient balance, issue tariff is deducted and gates open
automatically.
• If balance is not sufficient, account can be charged there only by paying cash .
• No person can exit library with a book without paying for it.

4. BASIC COMPONENTS USED
•MICROCONTROLLER 89S52
•LCD ( 2 BY 16 ) 5 BY 7 MATRIX
•MEMORY 24C02 ( SERIAL EEPROM )
•RF READER COIL & TAGS
•DC MOTOR (9V)
•KEYBOARD (MATRIX)

5. MODULES OF PROJECT
WE HAVE DIVIDED THE HARDWARE OF OUR
PROJECT IN TWO PARTS:
• MODULE 1: ENTRY GATE
• MODULE 2: EXIT GATE

6. ENTRY GATE
• THE ENTRY GATE OF OUR LIBRARY SYSTEM IS A
SIMPLE PASSWORD ENTRY GATE.
• A PASSWORD IS ASSIGNED TO EACH AUTHORISED
USER THROUGH WHICH ACCESS IS GRANTED
INTO THE LIBRARY.
• WE HAVE GIVEN THE ENTRY PASSWORD AS 1234
AND IF IT IS ENTERED WRONG MORE THAN 3
TIMES THEN MASTER LOCK WILL BE ACTIVATED
WITH THE BUZZER BEEPING AND THE MASTER
PASSWORD KEPT IS 9876.
• THE BASIC WORKING HAS BEEN SHOWN
THROUGH THE FLOW DIAGRAM.

8. EXIT GATE
• THE EXIT GATE OF OUR LIBRARY SYSTEM WORKS
WHEN A PERSON WANTS TO ISSUE A BOOK AND
EXIT THE LIBRARY
• THEN THE RFID READER INSTALLED AT THE EXIT
GATE READS THE RFID TAG .
• THE PERSON HAS TO ENTER THE PASSWORD AND
THE AMOUNT FOR ISSUE OF THE BOOK IS
DEDUCTED AND THE EXIT GATE OPENS.
• IF THE ACCOUNT DOES NOT HAVE ENOUGH
BALANCE THEN THE USER CAN RECHARGE IT.

13. HARDWARE SNAPSHOT

14. FUTURE SCOPES
• THIS PROJECT IS A DUMMY MODEL OF THE
LIBRARY SYSTEM IN WHICH THE CODING HAS
BEEN DONE FOR ONLY A MAXIMUM NUMBER
OF 15 STUDENTS AND 1 TEACHER.
• THIS COULD BE INCREASED IN THE
PROGRAMMING FOR FUTURE SCOPES OF
THIS LIBRARY SYSTEM & THE DATABASE CAN
ALSO BE MAINTAINED OF THEM.

17. PROBLEMS ENCOUNTERED
• WE WERE PLANNING TO INSTALL TWO RF ID
READER BOTH AT THE ENTRY AND EXIT GATES.
DUE TO FREQUENCY MISMATCHING SO ONLY
ONE RF ID COULD HAVE BEEN INSTALLED AT THE
EXIT GATE.
• THE CODING AND INTERFACING OF BOTH THE
MICROCONTROLLERS WAS A BIG TASK.
