Legitimate developers might use "CC checker" to mean Credit Card Validation (Luhn algorithm, BIN lookup) without any transaction attempt. A legitimate script looks like this: cc checker script php
// LEGITIMATE: Checks card format only
function luhnCheck($cardNumber)
$sum = 0;
$numDigits = strlen($cardNumber);
$parity = $numDigits % 2;
for ($i = 0; $i < $numDigits; $i++)
$digit = $cardNumber[$i];
if ($i % 2 == $parity) $digit *= 2;
if ($digit > 9) $digit -= 9;
$sum += $digit;
return ($sum % 10 == 0);
// This is legal and used for form validation.
