Nowadays, more and more people are using debit cards as a mode of payment. A reason for this is the convenience and speed of payment that it offers. Similar in look to a credit card, a debit card differs in that it is linked directly to a fund source such as a savings or a checking account. When the debit card is used, the payment is automatically deducted from the fund, alleviating possible major debts, as can be the case with a credit card.
