An ATM withdrawal is a process that allows individuals to take cash out of their bank accounts using an Automated Teller Machine. To make a withdrawal, a user inserts their bank card, enters their Personal Identification Number (PIN), and selects the amount of money they wish to withdraw. The machine then dispenses the requested cash. ATMs are widely available and can be found in various locations, such as banks, shopping centers, and convenience stores. Users should be aware of any fees that may apply, especially when using an ATM that is not affiliated with their bank.
