Product Description
Make sure the credit card number you have is accurate. cCard Check is a simple program used to check the validity of a credit card number that was generated using the Luhn (Mod10) formula. Most credit card numbers (including VISA, Mastercard, American Express, Diners Club and more) are generated using this algorithm and this program can check the number by verifying its length, prefix and checksum digit. This program does not authorize or approve credit card transactions. It only confirms that the number you have, whether obtained verbally or on a hand-written form, is a real credit card number. Works on color and monochrome devices.
