About Credit Card Validator

When you need to validate the authenticity of your credit card, you can use a credit card validator. This process holds significance, especially in sensitive situations. Fortunately, this process can be performed at home using our tool. All you need is a good internet connection.

The tool is simple to use. It will check the card number entered against the Luhn algorithm for testing the validity of the card number. This algorithm is based on a formula that is used for performing credit card number validation. It was established in 1960 and ever since then, it has been used for identifying types or incorrect entries in the card numbers. It’s used in the government and banking sectors.

The algorithm follows a standard procedure for validating credit card numbers. It removes the last digit from the number, reverses all digits, multiplies the odd digits in the number by 2, subtracts all digits greater than 9 from nine. Then, it ads all digits and take mode ten on this sum. If the answer is the same as the card’s last digit, the number is valid.

Don’t worry, our tool is secure. We handle sensitive information carefully. Our tool cannot be accessed by a third party hence, the information enter will not be shared.
