Answer:
overdraft protection
Step-by-step explanation:
An overdraft is a type of credit facility offered by banks to designated account holders. The credit facility allows an account holder to continue withdrawing fund when the account balance is zero. An overdraft also always payments of a larger amount than the prevailing account balance.
Like other loans, an overdraft attracts interest and a fee per each overdraft. The banks set a limit to the overdraft facility. Overdraft protection allows a bank to process payments that it would otherwise reject.
