AVS (Address Verification Service) and CVV (Card Verification Value) are used to measure the likelihood that they card being presented is legitimate. AVS is driven by the Zip Code of the billing address and CVV is a three digit number on the back of the card (or four digits on the front of American Express cards). The Setup AVS and CVV page allows the user to assign the weighting for AVS/CVV violation. The total of all violations equals the Total Fraud Score. The Score can be evaluated differently for each merchant account. This enables merchant to dictate the level of risk they will tolerate for each merchant account and transaction.
Setup AVS and CVV
Step 1: Choose Manage AVS & CVV from the FBI Tools menu.
Step 2: Click Setup Scoring. Enter the Domestic and International Score for each rule in the grid. When each of the AVS and CVV rules is true for a Sales transaction, the likelihood of Fraud increases. The higher the score, the riskier the transaction. Only positive numbers can be used for Scoring.
Step 3: Click Next to Manage Scoring Rules.
Step 4: Edit, Copy or Create new rules that govern the tolerated scores during a Sale transaction. Set the Total Fraud Score at a number that can be tolerated by your company. Anything above that amount will be Flagged for Review. Set the Total Fraud Score for Reject. Any above this number will not be Approved.
Step 5: Click the Enabled box. If Enabled is not selected, the AVS and CVV Rules will not appear in the Assign Rules to Accounts page.
Step 6: Click Next to Assign Rules to Accounts on the Global Policy Management page by choosing a Merchant Account and clicking the check box next to the applicable rule. You can use next filters to find the rule: Status, Assigned, Global Rule.
Global Policy Management
Step 7: Click Finish (or click Save) button to complete the assignment to merchant accounts.
Tools can be managed in two ways, the first is at the merchant level and the second is at a macro (global) level where all merchants can take advantage of fraud intelligence being used by other merchants. Global Policy is set by the gateway’s fraud intelligence team. This team uses current fraud trends and internal proprietary fraud intelligence systems to proactively create policies (controls, rules or filters) that could benefit the merchant population.
Most components of the policy are optional for merchants. Merchants can choose to assign them to their merchant accounts and subscribe to updates. By making part of the policy global, merchants can share their controls, rules and filters. Sharing some or all of a Fraud Policy helps cast a wider fraud net over known bad actors on the internet. All policies are shared anonymously.
