Answer:
Added overdraft protection feature to her checking account
Step-by-step explanation:
Overdraft protection is a form of credit facility offered by banks. The facility allows transactions such as checks, electronic payments, and transfers to go through even if the account has insufficient funds. Overdraft protection safeguards against bouncing payments, which attract heavy penalties.
Ann has a debit card. She can only shop with funds available in her accounts. Debit cards do not have an automatic credit feature. Ann should have activated overdraft protection on her debit card. She would have linked her savings account to her checking account so that the debit card can draw from her savings account. Savings accounts qualify for overdraft protection.
