A Credit Card Validator is a tool that helps check the validity of a credit card number by ensuring it follows the correct format. It uses algorithms like Luhn's algorithm to verify the number's structure. This is particularly useful for businesses or websites that handle online payments, as it reduces errors and helps avoid fraudulent transactions. By using a credit card validator, merchants can ensure that the information provided by customers is accurate and legitimate, making the payment process more reliable and secure.
