ATM stands for Automated Teller Machine. You can withdraw money from ATM at any time. Have you wondered what is the process behind it?
An ATM machine is a computer that has a mechanical dispenser for cash. The computer is connected to a secure network that can link up and validate the information with your bank account.

The entire ATM process starts when you insert your card. The mainboard then signals you to enter your PIN. After the PIN makes it back to the mainboard, the board sends off the unique EMV transaction code and your PIN to the processor through the I/O board and modem. The processor takes all of the information and routes it to the ATM network associated with your debit card. Each debit card is actually required to have two networks so that the transaction will work in case one network is down.
The ATM network gives your information to your bank that then determines if the transaction is valid. If the bank thinks it is, it sends an approval message back to the ATM. This entire process occurs every time you make a new input, like the amount of money you want to get out of the ATM.
When the process is completed, the mainboard initiates dispensing the cash and the dispenser transfers cash from the cassette one at a time. The dispenser mechanism is actually incredibly sensitive and is able to determine if the bills are dispensed properly in the right number. After your money is dispensed, you get a receipt and the mainboard prepares for the next transaction.
So that is it for today. Now you have understood how an ATM transaction is done and the process behind it
