Payment Processing Fraud Prevention

Reduce Fraud Losses with Real-Time Controls

Payment fraud controls are automated verification and monitoring tools that help detect and prevent unauthorized transactions. These controls apply proactive screening, rule-based restrictions, and risk signals to reduce losses and protect merchants and customers.

EDUCATIONAL INSIGHT

Effective fraud prevention uses layered controls tuned to business risk. The right combination helps reduce fraud and chargebacks without adding unnecessary friction.

SALES BENEFIT

Reduce fraud exposure with configurable controls that balance security and checkout speed.

AVS and CVV verification for baseline transaction screening.
Real-time velocity monitoring with configurable thresholds.
BIN and IP blocking to limit high-risk sources.
Customizable blacklists and whitelists for targeted controls.
ML-based fraud scoring with automated decisioning.

Fraud Controls Key Features

AVS/CVV Checks

Address & Code Verification

Verify billing address and card security code to reinforce transaction validation and limit chargeback exposure.

Velocity Controls

Transaction Monitoring

Monitor transaction patterns and set thresholds for counts, amounts, and time windows to detect rapid fraud attempts and unusual activity.

BIN/IP Blocking

Source-Level Prevention

Block high-risk BIN ranges and suspicious IP addresses, with geo-based restrictions for elevated-risk regions and automated threat blocking.

Payment Blacklists

Entity Exclusion Management

Exclude known fraudulent entities with customizable blacklists; manage blocked cards, emails, devices, and IP addresses in real-time.

Comparison: Advanced vs. Basic Fraud Controls

See how multi-layered fraud prevention outperforms basic security checks across coverage, configurability, and real-time response.

Frequently Asked Questions

Payment fraud controls are tools to detect and prevent fraudulent transactions. They include AVS/CVV verification, velocity monitoring, BIN/IP blocking, and blacklist management to protect merchants and customers from unauthorized activity.

AVS CVV checks verify the cardholder's billing address and card security code for each transaction. AVS (Address Verification Service) matches the address provided with the issuing bank's records, while CVV (Card Verification Value) confirms physical card possession.

Velocity fraud detection monitors transaction frequency and patterns for anomalies. It tracks how often transactions occur from a single card, IP address, or device within specified time windows to identify and block suspicious activity.

BIN IP blocking restricts transactions from risky card issuers (by BIN range) and suspicious IP addresses. It enables geo-based restrictions for high-risk regions and automated blocking of known threat sources.

Payment blacklists exclude known fraudulent entities from processing transactions. They can include blocked card numbers, email addresses, device fingerprints, and IP addresses, managed in real time through the Paygasus dashboard.
