Automatic teller machines, or ATMs, that are open 24 hours a day, seven days a week, allow account holders the option to access their money outside normal banking hours. To access that, it is necessary to have a debit card that works in those machines and a security code.
To use an ATM, it is necessary to insert the card into the slot. When prompted, the next step is to enter the account holder's security code, also known as a PIN. After that, the screen provides a menu of available transactions for the account holder to use, including withdrawing from the accounts that are connected to the card.
