how atm machine works

An ATM (Automated Teller Machine) works by securely communicating with your bank's network to process transactions.

• When you insert your debit/ATM card and enter your PIN, the ATM encrypts the data and sends the request to the bank's system via an ATM network.
• The bank verifies the PIN and account balance.
• Upon approval, the bank debits your account, and the ATM's cash dispenser releases the requested amount.
• A receipt is printed, and the machine prepares for the next transaction.
