      if($transaction->is_success()) {
        print "Card processed successfully: ".$transaction->authorization()."\n";

      }

## DESCRIPTION
    This is a module that adds functionality to [Business::OnlinePayment]. See
    [Business::OnlinePayment].

    The user instantiates a [Business::OnlinePayment] object per usual, adding
    in three processor directives

    *   fraud_detection

        Which Fraud Detection module to use.

    *   maximum_fraud_score

        FraudDetection drivers are expected to return a numeric "risk"
        factor, this parameter allows you to set the threshold to reject the
        transaction based on that risk. Higher numbers are "riskier"
        transactions.

    *   other driver-specific parameters.

        Consult the specific Fraud Detection module you intend to use for
        its required parameters.

    The $tx->submit() method is overridden to interpose a FraudDetection
    phase. A subordinate object is created using the same content as the
    parent OnlinePayment object, and a *Fraud Detect* action is run against
    that subordinate object. If the resulting fraud score is less than or
    equal to the maximum_risk parameter, the parent transaction will be
    allowed to proceed. Otherwise, a failure state will exist with a
    suitable error message.

## METHODS
    This module provides no new methods. It does, however override the
    submit method to interpose an additional Fraud Detection phase.
