A credit card is a special type of card that allows the customers to borrow money from their bank anytime and anywhere. Almost anything can be easily bought with a credit card as long as the store offering the material accepts the credit card. But, there is a limit on the amount of purchase that is set by the bank itself and it is known as the credit limit.

The respective bank lends the amount of money that is borrowed for any purpose as a credit on a specific rate of interest. If the customer fails to pay the amount borrowed within the timeline specified by the bank, later on, the principal amount has to be returned along with interest.

This algorithm is also used to protect the user accounts from malicious attacks.

This mathematical formula verifies a particular number against its included check digit. This check digit is appended on any partial account number to generate the full account number.
