Behavioral biometrics fraud prevention: Why faster payments mean faster fraud
Guest: Soups Ranjan
Today I’m talking about something that keeps getting more urgent across banking, fintech, ecommerce, and pretty much anywhere money moves quickly. Faster payments are creating faster opportunities for fraud. And once the money is gone, it is usually gone. That is why this conversation matters.
I sat down with Dr. Soups Ranjan, CEO and co-founder of Sardine, to talk about behavioral biometrics fraud prevention, real-time scam detection, and what good teams need to do before fraud happens, not after. Because at first glance, faster payments can sound like a product and customer experience story. But when you look closer, it is also a fraud containment story, a compliance story, and a decisioning story.
What I like about this episode is that we do not stay at the surface. We get into the mechanics of how digital payments fraud is changing, why old controls are struggling to keep up, and where behavior-based fraud detection can give teams a more realistic view of intent. That is the part that matters.
We also talk about the overlap between fraud and compliance, why cloud-based fraud prevention is becoming more important, and how marketplace KYC and fraud prevention are evolving as risk gets faster, more adaptive, and more expensive to clean up after the fact.
Here is what that means in practice:
- Behavioral biometrics fraud prevention helps teams spot risk earlier, before a payment or account action turns into a loss
- Real-time scam detection matters more when faster payments leave very little time to investigate after the fact
- Fraud and compliance can no longer operate like separate systems if both are trying to assess risk in the same customer journey
- KYC and fraud prevention need to work together when onboarding, account trust, and transaction behavior all influence exposure
What you’ll hear in this episode:
- Why faster payments are accelerating digital payments fraud and compressing response time for fraud teams
- How behavioral biometrics and behavior-based fraud detection help identify suspicious intent in real time
- Why real-time scam detection is becoming essential for modern payment fraud prevention
- How fraud and compliance are starting to converge in more practical and operational ways
- What Soups is seeing around marketplace KYC, cloud-based fraud prevention, and the future of fraud detection technology
You should listen to this episode if you:
- Work in fraud prevention, payments, risk, compliance, or trust and safety and need to adapt to faster-moving fraud patterns
- Want to understand how behavioral biometrics fraud prevention fits into a broader digital fraud prevention strategy
- Are responsible for ecommerce fraud prevention or payment fraud prevention and need stronger real-time signals
- Care about KYC and fraud prevention in marketplaces, fintechs, or digital platforms
- Want better fraud prevention strategies before scams, account abuse, or payment losses escalate

Episode notes & key takeaways
Why faster payments are creating faster fraud
Let’s break this down.
One of the clearest themes in this conversation is that payment speed changes the fraud equation. When money moves instantly or close to it, fraud teams lose the luxury of time. There is less room to review, less room to investigate, and a much smaller window to stop suspicious activity before the loss becomes permanent.
That is a problem.
Because a lot of traditional controls were built for a world where there was at least some delay between action and settlement. In that older model, teams could review, pause, or reverse more effectively. But with faster payments, criminals do not need long attack cycles. They need one good moment.
And this is where the risk starts to compound. Faster payments do not just speed up good transactions. They speed up bad ones too. Investment scams, account takeover, mule activity, social engineering, and first-party abuse all get more dangerous when the payout rail moves quickly.
Here is what stands out:
- Faster payments reduce the time available to catch digital payments fraud before funds leave the system
- Payment fraud prevention now depends more heavily on pre-transaction and in-journey signals
- Real-time scam detection is increasingly necessary when manual review cannot keep up
- Fraud prevention strategies have to assume losses will escalate quickly once criminals succeed
Why behavioral biometrics fraud prevention matters now
Here’s what’s actually happening.
If payment speed keeps shrinking the response window, then teams need better ways to recognize suspicious behavior earlier in the session. That is where behavioral biometrics fraud prevention becomes so important. Instead of relying only on static identity data or known bad markers, it looks at how someone interacts, navigates, and behaves in context.
And that matters.
Because a login can be technically valid and still be risky. A device can look familiar and still be under attacker control. A transaction can pass the usual checks and still be driven by coercion, scam behavior, or scripted manipulation. That is why behavior-based fraud detection gives teams something they often miss with traditional tools. It helps answer whether the interaction looks normal for that user, that action, and that moment.
Soups gets into why this kind of signal is especially useful in modern fraud detection technology. Not because it replaces everything else. But because it adds a real-time layer that can catch intent, hesitation, abnormal flow, or patterns that do not line up with legitimate use.
What good teams should pay attention to:
- Behavioral biometrics can strengthen fraud prevention by identifying unusual behavior before a payment is approved
- Behavioral biometrics fraud prevention works best as part of a layered decisioning strategy
- Behavior-based fraud detection helps surface signals that static KYC checks may miss
- Ecommerce fraud prevention and digital fraud prevention both benefit when behavior is evaluated alongside identity and device risk
Why fraud and compliance are moving closer together
This is one of the more practical parts of the episode.
For a long time, fraud and compliance were often treated like adjacent but separate functions. Different systems. Different teams. Different priorities. But when you look at how risk actually shows up in digital platforms, that separation makes less and less sense.
I have been seeing more of this lately.
A suspicious onboarding pattern is not just a fraud issue. It can also be a compliance issue. A risky payment pattern is not just about chargebacks or scams. It may also connect to mule behavior, money movement abuse, or broader financial crime concerns. So when fraud and compliance work from different signals, different workflows, or different assumptions, teams miss context they really need.
That is why the overlap between fraud and compliance matters so much now. Soups talks about this in a way that feels grounded in operations, not theory. The goal is not to force everything into one bucket. It is to recognize that the customer journey, the payment journey, and the risk journey are often the same journey.
A few practical implications:
- Fraud and compliance should share more context when reviewing account behavior and payment risk
- KYC and fraud prevention are more effective when onboarding signals flow into downstream monitoring
- Marketplace KYC programs need to consider both identity integrity and fraud exposure
- Cloud-based fraud prevention can help teams unify decisioning across products, payments, and compliance workflows
Why marketplace KYC and fraud prevention need to evolve together
This might not seem like a big deal. But in fraud prevention, it absolutely is.
Marketplaces and digital platforms face a particularly messy version of this problem because they are often balancing growth, trust, onboarding speed, and payment risk all at once. And when those businesses rely on fragmented controls, attackers usually find the seams pretty quickly.
Not exactly subtle.
A marketplace KYC flow might verify that a user can technically onboard. But that does not always mean the account is low risk. It does not mean the business is legitimate. It does not mean the payout behavior will make sense. And it definitely does not mean scammers will not adapt once they understand the thresholds.
That is why marketplace KYC and fraud prevention have to be connected. The initial verification step matters, but it cannot be the final confidence signal. Teams need continuous evaluation, better link analysis, stronger payment monitoring, and a way to connect onboarding data to what the account actually does over time.
Here is what good programs tend to do better:
- Marketplace KYC should be treated as the beginning of risk evaluation, not the end
- KYC and fraud prevention work better together when accounts are monitored throughout the customer lifecycle
- Fraud detection technology needs to connect identity, behavior, and transaction context
- Digital fraud prevention improves when platforms can respond to changing risk, not just initial approval status
Why real-time decisioning is the part teams cannot ignore
Honestly, this is probably the biggest operational takeaway.
A lot of teams already know fraud is getting faster. They already know scams are more sophisticated. They already know customer journeys are more vulnerable when trust and speed collide. The hard part is making decisions in time.
That is where real-time scam detection becomes more than a nice-to-have. It becomes the difference between interruption and cleanup.
Soups brings this back to a core point that holds up across fintech, ecommerce, and payments. The more quickly money can move, the more important it is to evaluate behavior, context, and risk signals before the action completes. Not hours later. Not in a report. In the moment.
Because once the fraud is successful, the rest of the work gets more expensive. Recovering funds is harder. Investigations take longer. Customers lose confidence. Compliance exposure grows. And internal teams end up spending time cleaning up something that should have been interrupted earlier.
The big takeaway from this episode is pretty straightforward. Faster payments are changing fraud operations whether companies are ready or not. That means fraud teams need stronger real-time visibility, better behavior signals, tighter alignment between fraud and compliance, and more practical ways to act before loss occurs. Behavioral biometrics fraud prevention is a big part of that conversation, not because it is trendy, but because it helps answer the question teams actually need answered in the moment: does this behavior look trustworthy or not?
That is the part that holds up.
