module VaultedBilling
  ##
  # Intermediary class used to translate your local credit card information
  # into data which VaultedBilling can recognize and use.
  #
  # Generally - and this is gateway specific - the only data which is
  # actually required is the card number and expiration date (expires_on).
  # Most of the other data is optional and may or may not be stored by
  # your gateway.
  #
  # Note: The vault_id is the unique identifier generated by your gateway
  # when you initially store the customer information.  This should be
  # kept and stored locally, related to your local credit card information.
  # If you generate a CreditCard object with a vault_id, it is assumed that
  # the card is already stored on the gateway and is not new information.
