ATM (Automatic Teller Machine) is a very essential tool required for the society in order to facilitate the need of safe transaction of money. Using this facility one can easily perform the various functions such as balance inquiry, withdrawn, money transfer etc. As this machine operation rely on bank cards, proper password, enough amount of money in one's account, certain verification and identification methods etc. It needs to be secure and having integrity of fine level right to its coding stage for optimum utilization of the service. In order to meet such requirements the coding languages used for it are modified here. In this paper, the code composed of VHDL language is suggested for this purpose of security.
