The Credit card validator step will help you check the following:

  • The validity of a credit card number. This uses a LUHN10 (MOD-10) algorithm.
  • The credit card vendor that handles the number: VISA, MasterCard, Diners Club, EnRoute, American Express (AMEX),...


  • Step name: the step name, unique in a transformation
  • Credit card field: the name of the input field that will contain the credit card number during execution
  • Get only digits? : Enable this option if you want to strip all non-numeric characters from the (String) input field
  • Output Fields
    • Result fieldname: the name of the (Boolean) output field indicating the validity of the number
    • Credit card type field: the name of the output field that will hold the credit card type (vendor)
    • Not valid message: the name of the output field that will hold the error message.
