Fraud Filter Reference
Unusual Order Filters

Filters Applied After Processing
Most filters are applied to the transaction request before forwarding the request to the
processor. The following filters are applied to the transaction results that the processor returns:
Unusual Order Filters
Unusual Order Filters identify transactions that exceed the normal size for your business.
Because fraudsters might not feel limited in their purchasing power, they sometimes place
orders that are much larger than the norm.
Total Purchase Price Ceiling Filter
What does the filter do?
This filter compares the total amount of the transaction (including tax, shipping and handling
fees) to the maximum purchase amount (the ceiling) that you specify.
The specified action is taken whenever a transaction amount exceeds the specified ceiling.
IMPORTANT: The Maximum amount per transaction setting in the Account menu controls
all transactions, even those that are less than or exceed the Total Purchase
Price Ceiling filter.
How does the filter protect me?
An unusually high purchase amount (compared to the average for your business) can indicate
potential fraudulent activity. Because fraudsters are not paying with their own money, they are
not price-sensitive.
Total Item Ceiling Filter
What does the filter do?
This filter compares the total number of items (or volume for bulk commodities) to the
maximum count (the ceiling) that you specify.
The specified action is taken whenever the item count in a transaction exceeds the specified
ceiling.
How does the filter protect me?
An unusually high item count (compared to the average for your business) can indicate
potential fraudulent activity. Fraudsters frequently attempt to order large numbers of attractive
items that can easily be resold.
NOTE: In addition, some items are more susceptible to fraud than others. For example, a
computer can be resold for much more money than can a pair of sport shoes. The
likelihood of selling the item quickly is also a factor.
