You can specify the input to the CreditCardValidator in two ways:
- Use the
cardNumberSourceandcardNumberPropertyproperties to specify the location of the credit card number, and thecardTypeSourceandcardTypePropertyproperties to specify the location of the credit card type to validate. - Use the
sourceandpropertyproperties 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, orCreditCardValidatorCardType.AMERICAN_EXPRESSCreditCardValidatorCardType.DISCOVER, orCreditCardValidatorCardType.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
- Visa: 4
- MasterCard: 51 to 55
- Discover: 6011
- American Express: 34 or 37
- Diners Club: 300 to 305, 36 or 38, 51 to 55
