What is ATM?
In simple words, ATM Card is a type of plastic card which is given by the bank for the convenience of the account holders. With the help of this card you can carry out your financial transactions like cash withdrawal, deposit, fund transfer and other bank related transactions at any time.
You don’t need to visit a bank for this. With an ATM debit card, you can perform many tasks, including online shopping, mobile recharging, and online bill payments.

Whenever you open an account with a bank, after a few days the bank sends you a place card called an ATM card. This card has a magnetic strip on it that contains all the user’s bank details.
When you insert this card into the ATM, the ATM contacts its server to check if your card is wrong and after checking all the details, you can do whatever you want.
You can do tasks like Balance Check, Mini Statement, Fund Transfer and many more. To complete the task, your ATM machine asks for the PIN of your card as per the input. After this, the bank checks these details whether the PIN you have entered is correct or wrong. Finally, if everything is correct, the transaction is completed by the ATM and your money is withdrawn.
