Description

When using 5817550003933609 as card number the check will fail. This number is
a valid Visa number, as used for Visa Carte Blue in France.

Solution:
change the Visa inner class to:

private class Visa implements CreditCardType {
private static final String PREFIX = "4,5,";
public boolean matches(String card)

{ String prefix2 = card.substring(0, 1) + ","; return ((PREFIX.indexOf(prefix2) != -1) && (card.length() == 13 || card.length() == 16)); }

}
