> (1) The onValidate() method of the CreditCardValidator class returns true for invalid inputs with null or unicode character such as 4\0\0\0\0\0\0\0\0\0\0\0\0\0\0. 
> (2) Also there is no length check on the input, therefore even invalid length inputs such as 9845 are accepted. 
> (3) There is no check for invalid issuer identifier, i.e.,  840898920205250 is accepted, where 84XXXX is not a valid issuer identifier
