ATM machines, what they are, how they work-1-..!!

Do you remember the last time you were on the road and found that your wallet was empty of any money, so you automatically went to the nearest “ATM” machine, and after a few minutes, you had at least enough to get home? Do you remember the last time you walked down the street with a huge number of bills to shop at a huge market that had ATMs inside? Hello, We are in the era of magnetic cards.

“ATM” or “ABM” or “Cash Point” or “Cashline” and others, they are all names for those machines that for many have become almost impossible to dispense with, because they have lost the ability to carry a huge number of banknotes or even a small number, they have become accustomed to They used it, and they became unable to buy with paper money or silver alike.

As a user or even as a non-user of “ATM” machines, you may have wondered how these machines work, and how you can withdraw money from your account in country X from an “ATM” machine located in the country?
Automated teller machines (ATMs)


The idea of ​​distributing cash out of business came from the needs of customers in Japan, Sweden, the United Kingdom, and the United States, where it began with a machine known as the “Computer Loan Machine” that gave a three-month advance at 5% interest to credit card holders, in 1966.


And the matter evolved over the years until a team of engineers led by “John Shepherd-Barron” came to manufacture the first “ATM” in history, which was placed in “Barclays Bank” in north London, specifically in its branch in “Enfield”. In 1967, it was first opened by English comedian Reg Varney. It worked by inserting paper checks that were cashed by the bank clerk, and they were marked with carbon so that the machine could read them and for security purposes.
The components of “ATM” machines are summarized in three things, which are “internal components – external components – operating system”. In this paragraph, we will start with the external or visible components and deal with us directly.


These components are divided into components or input elements and output elements, where the input elements are concerned with taking data or information from us, while the role of the output elements is in giving us the final results, and talking about the input elements are:
  • Card entrance: The first and most important elements of input into the machine. The card entrance is the part where the card is inserted, after which it scans the back of it to identify it.
  • Keyboard: The keyboard allows the card owner to first enter the password or what is known as “PIN” when asked, in addition to allowing him to type the amount of money he needs to withdraw it.

As for the output elements:

  • Loudspeaker: The loudspeaker provides some instructions to the card holder, as well as provides data and information, such as there is not enough money on the card, or the password is incorrect.
  • Display screen: The display screen accompanies the card holder at all stages, it shows him every step he must do from the beginning of entering the card until receiving the receipt. Deposit, mobile phone recharge, money transfer and more. Most of the machines that use “Lesed” Internet lines, or that we may call them – fixed Internet lines, use “Monochrome” or “CRT” screens. As for machines that work with dial-up, they use LCD or Monochrome screens as well.
  • Receipt stamp: You benefit from this element in that, after completing the withdrawal process, it prints a receipt containing the transaction data in terms of the amount withdrawn, the date of withdrawal, and the amount remaining in your account as well.
  • The cash dispenser: Of course, this is the most important component of the ATMs, and it’s also the heart of it, as it is the one that delivers the cash to you in a completely safe way, and it is always small in thickness.

I look forward to your participation in the comments with more information that I may have forgotten to write inadvertently.
