Final answer:
The debit card is the financial product that will not help you build credit history.
Step-by-step explanation:
The financial product that will not help you build credit history is the debit card.
A debit card is linked to your checking account and allows you to spend the available funds in that account. However, debit card transactions are not reported to credit bureaus, so they do not contribute to building a credit history.
On the other hand, secured credit cards, home mortgages, and regular credit cards can all help you build credit history as they involve borrowing money and making regular payments, which are reported to credit bureaus.
