What is the difference between a debit and a credit card?

The primary difference between a debit and a credit card is the source of funds. When you use a debit card, money is deducted instantly from your linked bank account. In contrast, a credit card allows you to borrow money from the bank up to a pre-approved limit, which you must repay by a specific due date. Key differences include:

• Debit cards use your own savings, while credit cards provide a line of credit.
• Credit card usage helps build your credit score, whereas debit cards do not affect it.
• Credit cards may involve interest charges if the full balance is not paid on time.
