ABSTRACT:
The main objective of this project is to develop an embedded system, which is
used to verify and authenticate the authorized
This project is implemented 8051/PIC based developed board interfaced with I-
Button, Keypad, buzzer and LCD, motor.
The i-Button is a computer chip enclosed in a 16mm thick stainless steel can.
Because of this unique and durable container, up-to-date information can travel with a
person or object anywhere they go. The steel i-Button can be mounted virtually anywhere
because it is rugged enough to withstand harsh environments, indoors or outdoors. It is
small and portable enough to attach to a key fob, ring, watch, or other personal items, and
be used daily for applications such as access control to buildings and computers, asset
management and various data logging tasks.
Whenever the customer open an bank account with required identification proof
after that bank give one i-button to the customer for further accessing bank process with
that reference of customer account identity number through i-button.
Whenever the customer enters into the bank/ATM, he has to keep his I-button
to the reader which is attached to our microcontroller based embedded System. And
enters the password through the keypad interfaced. At that moment the reader will checks
weather the information of the customer is correct or not and then it will decide whether
to give access to that particular person or not. If the information of the customer is correct
then he will be permitted inside otherwise he will not permit inside and switched on the
buzzer. If the password is correct then go to further process like deposit, withdraw,
balance enquiry. And the information of the access system will be displayed on the LCD
which we embedded to our board.
This project uses regulated 5v, 750ma power supply. 7805 three terminal voltage
regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify
the ac output of secondary of 230/18v step down transformer.
