(*) : Since JCB cards that start with a 3 have 15 digits, and that
American Express cards start with a 34 or a 37, and also have 15 digits,
JCB absolutely MUST be AFTER American Express in your Media type setup
order. If it came before, all American Express cards would be interpreted
as JCB.
(**) : No Modulus 10 Validation.
