A cash withdrawal is the process of taking money out of a bank account, typically using an Automated Teller Machine (ATM) or by visiting a bank branch. This allows account holders to access their funds in physical currency, which can be used for various transactions or personal expenses. To perform a cash withdrawal at an ATM, a user must insert their debit or credit card, enter their Personal Identification Number (PIN), and select the amount they wish to withdraw. The machine then dispenses the requested cash, and the transaction is recorded in the account holder's bank statement.
