Get Started FreeMerchant Solutions · Risk & Protection
Fraud finds high-risk businesses first. We build fraud protection into the payment processing itself: every transaction screened in real time, your account monitored 24/7, and every decision tied back to the number that keeps your account open — your chargeback ratio.

Fraud protection
How it works
Merchant fraud detection is not a single filter — it is a pipeline that screens every transaction in milliseconds, before funds ever settle. Here is what happens each time a customer pays you:
Every decision feeds back into the models: confirmed fraud, false positives, and new attack patterns all retrain the system, so tomorrow's screening is sharper than today's. The diagram below shows how the layers fit together.

Monitoring
Fraud detection screens individual transactions; merchant fraud monitoring watches the bigger picture. That matters most for card-not-present businesses, where a quiet Friday-night attack could otherwise settle before anyone opens a dashboard on Monday.
We monitor your transaction activity 24/7 with:
If you accept bank transfers, monitoring now extends beyond cards — Nacha's 2026 ACH fraud monitoring rules set new requirements there too, and our screening covers both channels.
Monitoring that lives inside your payment processing learns your business's normal behavior and defends it around the clock, without adding manual review work for your team.
Card fraud
Stolen card numbers are the most common threat online merchants face, and no single tool stops them. We layer card-specific defenses across every transaction:
When a stolen-card transaction slips through, the real cardholder disputes the charge, and you lose the product, the revenue, and a point against your chargeback ratio. Stopping credit card fraud at authorization is always cheaper than fighting the dispute afterward.
What's included
High-risk merchants
High-risk businesses do not just see more fraud attempts — they face harsher consequences when fraud gets through, because banks and card networks watch their chargeback ratios closely. The best fraud prevention for a high-risk merchant is the kind built into the processing relationship itself.
We pair industry-specific risk models with cross-merchant detection that recognizes bad actors already flagged across our network. Fraud behaves differently vertical by vertical — compare online fraud patterns in the travel industry with card-testing attacks on subscription billing — so screening tuned to your industry catches what generic filters miss.
These tools come bundled with your high-risk merchant account, so screening, payment processing, and chargeback management work as one system instead of three vendors.
Fraud types
Merchant fraud is an umbrella term covering several distinct threats, and each takes a different defense:
Fraud in any of these forms costs you product, revenue, and chargeback standing. Get accurate merchant fraud detection when you choose PayKings.
