Business::FraudDetect - A cohort to Business::OnlinePayment
=head1 SYNOPSIS
my %processor_info = ( fraud_detection => 'preCharge',
maximum_fraud_score => 500,
preCharge_id => '1000000000000001',
preCharge_security1 => 'abcdef0123',

)

expiration => '0100',
name => 'John Q Doe',
);

} else {

}
=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.
