INTRODUCTION

What is ATM?

Auto teller machine, mostly referred to as “ATM”, is

a machine that automatically provides cash without the aid of a bank representative, as well as performs other banking services upon the insertion of a special card that is issued by the bank you applied to.

Input devices are any hardware or peripherals that allow users

to insert/put data into the computer to get certain results.
An input allows users to interact and feed instructions and data to the computer for processing, displaying, storaging and sending in certain scenarios.

An Output device is any hardware or peripheral that allow

users to remove or display the processed data (information) from the computer system. Each output devices serves a specific purpose just as the input device e.g. Speakers to output audio.

The Monitor is the output device that displays the interaction happening

between the user and the system. In this case, it allows the card holder to be able see what options they have selected. The most ATMs monitors have a touch screen systems, it means ATM monitors play two different roles, namely input/output.

Process Process Process Process

In this first step, the

cardholder begins by inserting a plastic card (provided by their bank) into a card reader. Many ATMs go into a power saving mode, so when the plastic card is inserted, the ATM works with fully awake mode. Then the cardholder has to insert their card’s PIN (Personal Identification Number) code via the ATMs keypad. Most modern plastic card’s PIN code includes 4 or 6 digital numbers.

The second step is the Checking Process.

The Checking process is the direct involvement between the ATM and host processor. When the cardholder enters either PIN code, the account information is automatically sent to the main host processor. Host processor is a gateway through which various ATMs are networked.

In this process, the cash dispending

mechanism has an electric eye sensor that counts each bill before giving to the customer. Besides the electric eye sensor, there is also has a sensor that evaluates the thickness of each bank note. In some case, if two notes are stuck together, cash dispenser rejects damaged notes to the cash box where this notes saved first, then cash dispenser continues to work with another cash box. A general ATM has 4 cash boxes in it.

In this printing process, ATM gives a

receipt to users about the transaction that he or she has just carried out with this ATM. First, the ATM prints a hard copy of the receipt, then saves it inside of the storage device. After this, the ATM sends it to the host processor. This process continues step by step, if any errors have occurred during the process of printing, the ATM would automatically send feedback to the bank organization employees.

The final step that occurs during the

withdraw money process by an ATM is cleaning process. In this step, the ATM automatically clears all of the information about visa card and cardholders. Firstly, the ATM rejects the customers’ visa card via card reader, then it clears all of the temporary files, sessions, variables that recognized by sensors. After finishing all of the cleaning process, the ATM starts to work with sleeping mode.

Voice recognition is the field of computer science that is

involved with designing computer systems that can recognize and analyze spoken words. But voice recognition means only that the computer can take dictation, not that it understands what is being said exactly. According to the users, this technology needs more improvements.
