- Use the
cardNumberSource
andcardNumberProperty
properties to specify the location of the credit card number, and thecardTypeSource
andcardTypeProperty
properties to specify the location of the credit card type to validate. - Use the
source
andproperty
properties to specify a single Object. The Object should contain the following fields:-
cardType
- Specifies the type of credit card being validated.In MXML, use the values:
"American Express"
,"Diners Club"
,"Discover"
,"MasterCard"
, or"Visa"
.In ActionScript, use the static constants

,CreditCardValidatorCardType.VISA
, orCreditCardValidatorCardType.AMERICAN_EXPRESS
CreditCardValidatorCardType.DISCOVER
, orCreditCardValidatorCardType.DINERS_CLUB
. -
cardNumber
- Specifies the number of the card being validated.
