Debit and credit cards are payment instruments that enable cashless transactions, but they differ in how the funds for those transactions are provided.

A debit card is directly linked to the user’s current (checking) account. When a payment is made using a debit card, the funds are automatically deducted from the available balance in the account. This means that the user can only spend money that is already available. In certain cases, if an overdraft facility has been approved by the bank, the user may access additional funds within the agreed limit, although these are still tied to the user’s bank account.

A credit card, on the other hand, represents a form of a revolving credit product issued by a bank. The user is granted a specific credit limit, within which they can make purchases or withdraw cash, in accordance with the agreement with the bank. The funds used through a credit card are borrowed from the bank and must be repaid under defined repayment terms. Depending on the type of card and contractual conditions, repayment may be made in full within a grace period or in installments, with interest applied after the interest-free period expires.

The key difference between debit and credit cards lies in the source of funds: a debit card uses the user’s own money, while a credit card uses the bank’s funds within an approved credit limit.

From a financial management perspective, debit cards provide direct control over spending, as they limit transactions to the available account balance. Credit cards offer greater flexibility in terms of liquidity and deferred payments, but they also require responsible use to avoid additional costs such as interest and fees.

In practice, the choice between debit and credit cards depends on the user’s financial needs, cash flow management, and the specific terms set by the bank for each product.
