Credit Card Validator

A Credit Card Validator is a tool used to validate the accuracy of credit card numbers. It works by checking the number against the industry-standard Luhn algorithm, which is used to identify whether the number is valid or not. The validator can also be used to identify the type of credit card, such as Visa, Mastercard, American Express, etc.

This is important for businesses that accept credit cards as payment for goods or services, as it helps to ensure that all transactions are secure and legitimate. Additionally, the validator can be used to detect any potentially fraudulent activity on a cardholder's account, helping businesses to protect themselves from financial losses.
