Credit Card Validator
Validate your Credit Card Online
|Credit Card Type||Credit Card Number|
Credit card numbers are generated according to specific rules. This allows merchants to verify the card number's validity before accepting a customer's payment. The calculation to compare the credit card number with your checksum is called the Moon algorithm. You can also save time using the online credit card validator Prepostseo to calculate the checksum.
How do I perform a manual check?
Enter the last digit of your credit card number. This is the checksum number that you will use to verify the remainder of the credit card number.
Enter each digit of the credit card number, starting with the digit to the left of the checksum and moving to the left. If the credit card number consists of 16 digits, double the number of each digit in odd places, working from right to left, before adding it to your list.
In the case of credit cards with 15 digits, they duplicate the digits at points of the same position. If you double the results of digits of a number greater than 10, add the two digits of the new number together and write this result to your list. For example, if the number on the map is seven, duplicating it will result in 14. In total, two digits will be five.
Sum up your list of numbers. Don't include the checksum in your total. The credit card has a valid number if the total amount can be divided by 10. Otherwise, it would help if you did not process credit card transactions.

Importance of Credit Card Verification
It is important to remember that whenever fraudulent cards are used, the merchant loses. The customer of the stolen credit card is not connected, and credit card companies are generally unaffected. However, the merchant usually remains aloof from the product or service provided and the resources needed to detect fraud and deal with the credit card company. And if too many fraudulent transactions occur, you may incur higher processing fees, expensive chargebacks, or even lose your merchant account and your ability to conduct business.
But you can reduce these risks with some automation, and we can help you! Just use our online card verification tool, and our tool will help you fight fraud and maximize your credit card sales.
