The CreditCardValidator class validates that a credit card number is the correct length, has the correct prefix, and passes the Luhn mod10 algorithm for the specified card type. This validator does not check whether the credit card is an actual active credit card account.

You can specify the input to the CreditCardValidator in two ways:

Use the cardNumberSource and cardNumberProperty properties to specify the location of the credit card number, and the cardTypeSource and cardTypeProperty properties to specify the location of the credit card type to validate.
Use the source and property 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.MASTER_CARD, CreditCardValidatorCardType.VISA, or CreditCardValidatorCardType.AMERICAN_EXPRESS CreditCardValidatorCardType.DISCOVER, or CreditCardValidatorCardType.DINERS_CLUB.
- cardNumber - Specifies the number of the card being validated.

To perform the validation, it uses the following guidelines:

Length:

Visa: 13 or 16 digits
MasterCard: 16 digits
Discover: 16 digits
American Express: 15 digits
Diners Club: 14 digits or 16 digits if it also functions as MasterCard

Prefix:

Visa: 4
MasterCard: 51 to 55
Discover: 6011
American Express: 34 or 37
Diners Club: 300 to 305, 36 or 38, 51 to 55

Parámetros

	`validator:CreditCardValidator` — The CreditCardValidator instance.

	`value:Object` — A field to validate, which must contain the following fields: `cardType` - Specifies the type of credit card being validated. Use the static constants `CreditCardValidatorCardType.MASTER_CARD`, `CreditCardValidatorCardType.VISA`, `CreditCardValidatorCardType.AMERICAN_EXPRESS`, `CreditCardValidatorCardType.DISCOVER`, or `CreditCardValidatorCardType.DINERS_CLUB`. `cardNumber` - Specifies the number of the card being validated.

	`baseField:String` — Text representation of the subfield specified in the value parameter. For example, if the `value` parameter specifies value.date, the `baseField` value is "date".
