It has been almost four decades that banks and other financial organizations have been gradually computerised, in order to improve service and efficiency and to reduce cost. The birth of Electronic Fund Transfer and Automated Teller Machines has given rise to 24-hour banking and a greater variety of services for the customer. This method uses a computer to transfer debits and credits, with the help of electronic pulses, which are carried through wires either to a magnetic disk or tape. ATM

People use ATM for various purposes such as money withdrawal, checking balance, changing password etc. Since it mainly deals with people's money, it has to be a secure system on which we can rely. We have taken a step towards increasing this security and integrity by trying to implement the functioning of an ATM using VLSI-based programming, HDL(Hardware Description Language).The conventional coding languages such as C,C++ are replaced by VHDL(Very High Speed Integrated Circuit Hardware Description Language) so that the code cannot be easily hacked or changed. This article consists of an insight into the various functions that can be performed using an ATM, a brief description of the Coding and the obtained simulation results. It also consists of the implementation of the code using FPGA Kit (Spartan3;.
