Abstract:
This project is about money transfer system for ATMs. i.e., account holder can enter the key(password) in his mobile. The controller on transmitter side will encode key to some some addres. On the other side, that is further decoded by DTMF decoder, then to Microcontroller. Microcontroller will decide how much money has to be drawn for that particular key, as according to the program written in it.
Note that,Secret Key (password) is known only to account holder.
This module is interfaced with ATM machine, so end user can draw that particular amount using smart card. After money drawn, Acknowledge is sent to the account holder which gives details of
1.How much money drawn
2.What is the remaining amt in that account
This is done by using GSM technology. This is a secured and efficient, time saving ,fast response and very useful in emergency cases. so that account holder can transfer money to any of his friends from where ever he is, and get the result to his mobile after access.
This module includes both transmitter, receiver.
In this we use 89c52 microcontroller , power supply unit, keypad , mobile phone,APR9600 VOICE CHIP, audio amplifier,and control circuitry,etc.,
Software requirement:
KEIL micro vision IDE tool,
Flash programmer,
Embedded C,
Protieus software for circuit simulation.

give some ex diagrams and videos for hoe its work.....
