HOW TO WORK ATM

ATM is a data terminal device that has two input and four output devices. Just as a data terminal, ATM must have a connection, connect, and communicate through a host processor (central processing). Central process that is accompanied by an Internet service provider (ISP) that serves as a gateway route to get to control every aspect of ATM network and make the kinds of functions for the ATM card holders (people who want money.)

In general, the central processes that support can be via Leased-line or line of contract (lease) or dial-up machine (telephone). Leased-line machines connect directly to the central process through the four-wire (four-wire), point-to-point, dedicated telephone line (telephone line option). Dial-up ATMs connect to a central process through a normal telephone line using a modem and connection toll free number, or through Internet service providers who use local access numbers. Leased-line ATMs recommended for use in a solid location for thru-put capability job market is relatively heavy, and dial-up ATMs recommended for use in stores or locations that are not crowded where the use of just taking money. The cost required for a dial-up ATM machine is less than half leased-line ATM machines. Operating cost dial-up ATM machine is also only a fraction of the cost of operating leased-line ATM machines.

At the time the card holder wants to do an ATM transaction, the person must provide the information needed by the detector card and keypad are available. ATM machines will forward this information to the central process, through data communications channels that have been appointed to conduct the transaction request to the bank in accordance with a user card. If the cardholder wants cash withdrawal, the center of the process will charge transfer (electronic funds transfer) to replace the central bank service fee from the customer-owned bank. At the time the cost has been transmitted to the central bank, then the processor will send the code approval (approval code) to the ATM as the machine authorization to issue cash. Then the processor will send data of financial transactions to the cardholder's home bank ATM users, usually the next business day. In this case, the Bank is home to replace the entire cost of the ATM machine.
