Credit Card Online Validator

Credit Card Online Validator is a practical tool for the users who need to check the validity of a credit card number. It allows you to confirm if a credit card number is valid by using a remote server that processes the request.
The validity of a credit card number is important for the companies or websites that process online payments in order to filter out the fake purchase orders. This operation is based on the Luhn algorithm which applies a checksum formula in order to validate the identification number.
This tool allows you to find out if the entered credit card number is valid according to the Luhn algorithm and displays the result in the main window. Unfortunately, it cannot detect the card maker and you need to select it from the main window before sending the request.
You can use this tool for VISA, MasterCard, American Express and Dinner Club International credit cards. In our test, it required insignificant resources and provided the verification result in a few seconds.
However, the program’s effectiveness is questionable since all the verified numbers were marked as invalid by the server. Moreover, even the real card numbers and the default samples of the above mentioned companies returned the same negative result.
Since there are many web-based apps or programs that can check the validity of a credit card by using the Luhn or MOD 10 algorithm, this program seems too pricey for most users who only need to check a few numbers.
Taking into consideration the results and the price, Credit Card Online Validator should not be your first choice when you are looking for a card number validation tool.
