MAJOR COMPONENTS OF ATM

ATM machine do have various major components which are responsible for the functioning of the Automated teller machine.

CARD READER:

If there will be no card reader, then ATM card can not be read so no transaction can be done by machine.

ATM card is required to swipe through this card reader slot.

After swiping card it captures the account information through magnetic stripe of ATM.

After retrieving the correct information of your account, card reader send this information to the host processor for further process.

HOST PROCESSOR:

Host processor is the heart of ATM machine.It contacts the bank server and retrieves your

account details such as available balance, previous transactions, PIN etc

It verifies your PIN number and if it matches with the provided PIN number from the bank server, you are allowed to make the transaction.

To take your PIN and other requests form user, there will be a keypad or touch pad.

KEYPAD OR TOUCH PAD:

Key pad or touch pad is responsible for taking input from the user.

On this pad, numbers and few other keys such as Clear, OK etc., will be placed.

Key pad transfers your inputted data to host controller to process the request.

SPEAKER:

Speaker is placed in ATM machine which is responsible for audio alerts.

When you press any key, this speaker confirm the pressing of key by producing a beep sound alert.

It assures you that the key pad is working.

So speaker is also very important part of ATM machine.

LCD or CRT screen:

Another major integral part of the ATM machine is its Cathode Ray Tube (CRT) or Liquid Crystal Diode (LCD) screen.

CRT or LCD screen is responsible for visual display of your transactions.

It is responsible for displaying your name, entered amount, account number etc.

Without CRT or LCD display screen, the transactions from ATM machine would have become more difficult.

Receipt printer:

Receipt printer is responsible for the printing of your transaction's receipt.

It will print whether the transaction is successful or not.
