What is an ATM? How the ATM works?

An ATM is an electronic device used only by customers of banks for money transactions (especially withdrawals). For ATM users to access their accounts, banks provide a special plastic card (Debit card or Credit card) in which the user’s information is already encoded on a black strip which is a magnetic strip on the back of the card. An ATM is actually a data terminal that is connected to a host processor. Acts as a link between the host processor and the ATM.

To use an ATM, by inserting the ATM card into it and writing the 4-digit code and the amount of money to be withdrawn, the host connects to the processor, and with its help, the user can withdraw money without going to the bank. ATMs have input devices like card readers and keypads and output devices like speakers, display screens, receipt printers, and case depositors.
