A debit card lets you pay for purchases by taking money directly from your checking account. Used safely, it can help you practice budgeting, track spending, and avoid carrying large amounts of cash. Because the card connects to real money, protecting it is part of personal safety and financial health.
Good habits now can prevent fees, fraud, and stress later.
Key Facts
