Falcon Fraud Detection
Neural network technology.
Visa security incorporates Fair Isaac's Falcon Fraud Manager, a neural network platform that utilizes sophisticated fraud risk scoring to capture relationships and patterns often missed by traditional fraud detection methods. This advanced system allows you to design customized anti-fraud strategies to successfully detect and avoid fraudulent activity. The system also provides operational and statistical reports to help you measure the success of your anti-fraud program.
Primary system components include:
Falcon Debit. In conjunction with the Visa authorization system, the Falcon Debit scoring engine uses complex statistical models to calculate a fraud score for each transaction. If the score indicates a high probability of fraud, the system can create and send a fraud case to an analyst for review, block subsequent transaction attempts, or both. The fraud score also may be used to make real-time authorization decisions.
Falcon Expert. Falcon Expert provides the ability to define rules for automated fraud prevention protocols. This customizable feature allows the addition of other relevant transaction data fields, in addition to the fraud score, when determining fraud actions.
Flash Fraud Rules
Flash Fraud Rules provide a parameter-driven set of rules to help catch and block suspect transactions falling into specific risk categories. Flash Fraud Rules are temporary rules to catch isolated fraud and stop authorization requests prior to approval. They may be used alone or in conjunction with Falcon.
The following fields may be used to block fraudulent transactions:
- Merchant country code
- Merchant category code
- Merchant ZIP code
- Acquiring network ID
- PAN entry mode
- Transaction amount range
- CVV checked indicator
- CVV result
- BIN
- Prior Falcon score
- Visa Advanced Authorization Risk Score or Risk Condition Code
- Visa CAMS alert ID
Call Center Services
Fraud Call center services.
Visa Cardholder Support Services (CSS) offers a high quality, turnkey fraud call center solution for financial institutions using Falcon Fraud Manager. At your option, you may use CSS support around the clock (full-service plan) or part-time (shared-service plan). Whichever option you choose, Visa fraud analysts monitor your fraud scores, notify cardholders of suspicious activity, and respond to cardholders' inquiries related to their fraud situations.
Visa fraud analysts monitor suspicious transaction activity and, based on rules defined by your financial institution and fraud scores, call your cardholders if they suspect unauthorized use. If a cardholder is unavailable when a fraud analyst calls, the analyst leaves a message including a toll-free number, unique to your financial institution, to encourage a return call. Analysts also work proactively to block confirmed fraudulent or high-risk transactions, helping to minimize fraud losses.
Hot card/card activation services.
In addition, CSS supports hot card statusing and card activation services. CSS can accept lost/stolen card notifications and card activation requests 24/7 from your cardholders. Around-the-clock hot carding helps protect your cardholders and financial institution from potential fraudulent activity. Full-time VRU capabilities enable cardholders to activate their new or reissued cards whenever it’s most convenient for them.
Authorization Services
Authorization edit checks
Risk edits and authorization processing options help reduce your fraud exposure. Edit checks may be set at the financial institution, card group, or individual cardholder level. You may set limits separately for cash and POS activity, and timeframes may be set for single- or multiple-day periods.
Visa Fraud Protection Programs
For greater card program protection and reduced fraud, these programs validate additional data in the authorization message:
- Cardholder Verification Value (CVV). Validates a unique three-digit code on the magnetic stripe of all cards to detect counterfeit or re-encoded cards.
- Cardholder Verification Value 2 (CVV2). Verifies a unique value, printed on the reverse side of the card, to reduce fraudulent card-not-present transactions.
- Dynamic Cardholder Verification Value (dCVV). Validates a dynamic three-digit code provided by the chip on a contactless card to detect fraud.
- Address Verification Service (AVS). Enables merchants to confirm a cardholder's billing address to prevent fraud in the card-not-present environment.
Verified by Visa (VbV)
VbV makes Internet purchases safer by authenticating a cardholder's identity in real time during an online Visa card transaction. Cardholders are asked to enter a password to validate their identity during the authorization process.
Visa Advanced Authorization
Visa Advanced Authorization, an enhancement to the VisaNet authorization message, is a risk evaluation system that provides risk information directly for 100 percent of VisaNet-processed authorizations (initiated with a U.S.-issued Visa card). Robust risk information enables you to make real-time decisions that can potentially stop losses with the first transaction. Visa Debit Processing Service has developed fraud rules to stop activity based on Visa Advanced Authorization scores.
Stand-in processing
Visa authorizes transactions on behalf of your host system when it is unavailable or when you have chosen Visa to process a certain transaction on your behalf. Before authorizing a transaction, Visa reviews your cardholder file, your specified limits, and your transaction data check options to handle the transaction according to your specifications
Suspect activity reporting
A suite of reports can help identify excessive or abnormal cardholder activity levels. Configurable reports can monitor transaction counts and dollar limits for single- or multiple-day periods.
