=head1 DESCRIPTION

This is a module that adds functionality to Business::OnlinePayment.  See L<Business::OnlinePayment>.

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

=over 4

=item *  fraud_detection

Which Fraud Detection module to use.

=item *  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.

=item * other driver-specific parameters.

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

=back

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 I<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.

=head1 METHODS

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