The automated teller machine is simply a data terminal with two input and four output devices. These devices are interfaced to the processor. The processor is heart of the ATM machine. All the ATM machines working around the world are based on centralized database system. The ATM has to connect and communicate with the host processor (server). The host processor is communicating with the internet service provider (ISP). It is the gateway through all the ATM networks available to the card holder.

When a card holder wants does an ATM transaction, user provides necessary information through card reader and keypad. The ATM forwards this information to the host processor. The host processor enters the transaction request to the cardholder bank. If the card holder requests the cash, the host processor takes the cash from the card holder account. Once the funds are transferred from the customer account to host processor bank account, the processor sends approval code to the ATM and the authorized machine to dispense the cash. This is the way to get the amount on ATMs. The ATM network is fully based on centralized database environment. This will make life easer and secured the cash.
