For merchants, protecting revenue now demands a layered fraud strategy that blends secure payment practices with intelligent digital defences.

This overview breaks down the two core approaches emerging in the market: secure payments and AI-driven analysis, along with the tools that sit within each category.

Secure Payments

This group of technologies focuses on strengthening the transaction itself. Rather than examining user behaviour, secure payment solutions harden the payment flow; making it harder for fraudsters to slip through unnoticed.

Tokens

Tokenisation replaces sensitive card data with unique identifiers that have no exploitable value to criminals. It limits the damage of stolen credentials and underpins safer digital payments.

Geolocation

Merchants compare a shopper’s claimed location against their real-time position. If there is a mismatch or an unusual access pattern, it can trigger alerts or step-up authentication.

3D Secure

This additional layer of authentication shifts risk decisions to issuers and helps validate users before transactions are approved; particularly effective for card-not-present commerce.

Velocity Checks

Velocity rules detect unusually fast or repeated transactions, blocking automated fraud attempts such as card testing or credential stuffing.

Artificial Intelligence

While secure payments reinforce the process, AI focuses on understanding the person behind the transaction. These tools learn, analyse and adapt; identifying suspicious behaviour before fraud succeeds.

APIs

API-driven integrations allow merchants to plug into fraud databases, third-party verification services and real-time screening engines, strengthening defences across the payment journey.

Biometrics

Fingerprint, face or voice recognition verifies that the person completing the transaction is genuine, reducing reliance on passwords that can be stolen or guessed.

Machine Learning

Algorithms monitor historic and live transaction data, spotting anomalies faster than manual review. As fraud patterns evolve, ML models adapt without needing to be rewritten.

Behavioural Biometrics

Instead of physical traits, these systems look at how users type, swipe or navigate. Subtle discrepancies can reveal whether a real customer or a bot is behind the action.

Behavioural Analysis

By profiling typical customer actions, merchants can pinpoint when something feels “off”, including irregular spending behaviour or unusual navigation; prompting additional verification.

Chargeback Resolution

Specialised tools help merchants investigate, contest and automate the resolution of disputed transactions; reducing revenue leakage from illegitimate chargebacks.

Fraud prevention is no longer about choosing one tool. It requires both stronger payments architecture and smarter intelligence.

Secure payment methods build resilience at the point of transaction, while AI-driven analytics lets merchants detect fraud before it becomes loss. Together, these approaches help businesses stay ahead of evolving threats, protect margins, and maintain trust with their customers.
