how to overdraft checking account
Use your debit card for purchases. If the purchase exceeds the amount of money in your checking account you will overdraw your account. For example, making a $50 purchase with your debit card when your checking account has only $30 may result in an overdraft. Use your debit card to withdraw money. Withdrawing more money than your checking account holds results in an overdraft. Step 3. Write a check for more money than your checking account can supply. If you write a check for $60 and your checking account has only $55 in it, you will overdraw your account.
