In the case of a traditional credit card, the customer makes a purchase and charges the amount to a credit card. In turn, the cardholder becomes liable for the outstanding debt within a specified time-limit. If he is not able to repay it within the grace period then the card issuing company charges the customer a predetermined rate of interest. A very common phenomenon in such a case is excess expenditure by the customer, leading to consequent default.
However, when it comes to prepaid cards the consumer has to buy the credit card from a company and loads it with an amount of money. The consumer is then able to use the credit card to purchase goods but is strictly limited to the prepaid amount of money loaded on the card. Hence, these types of credit cards are also known as 'Stored-Value Cards'.
Prepaid credit card helps consumers plan their expenditure in advance, and to limit spending strictly within a budgeted amount.
For this reason this type of credit card is known as free prepaid credit card. However this claim of 'free card' becomes a sort of a misnomer when the companies start charging registration and other associated fees. Whenever a person reloads more money into his card, the company charges an extra fee to the customer.
