Sardine | Push Payment Fraud: Reshaping the Digital Payment Experience

What’s up fraud fighters, and welcome to Fraud Forward!

Alright, I am going to say this plainly. Push payment fraud is not “the next big thing.” Push payment fraud is the big thing right now. And when losses in the Americas are being talked about at the $102 billion level, that is not a scary headline. That is a full-on industry reckoning.

In this solo episode, I am unpacking what I am seeing, what institutions are feeling, and where I think we have to recalibrate fast. Because authorized push payment scams are reshaping the digital payment experience whether we want them to or not. And the hardest part is that real-time payments fraud compresses the intervention window down to almost nothing.

The core mechanics are brutal. The customer authorizes the transfer. The authentication passes. The transaction looks clean on the surface. The harm is happening because the customer is being controlled through social engineering, impersonation, and urgency cues. That is why APP fraud losses keep climbing and why customer reimbursement pressure keeps landing on banks and fintechs.

And fraud fighters, I want to double click on something I see leaders miss. This is not “just a Zelle problem.” Zelle fraud risk is real, but the bigger story is peer-to-peer payment fraud and RTP fraud exposure across instant rails. Once funds move, they can hop accounts fast, and recovery gets messy fast. That is payments ecosystem risk in motion.

Now let’s talk about the tension point. Customers want speed. Customers want seamless. Customers expect transfers to feel like texting. And if you slap heavy friction everywhere, you will break customer experience and watch conversion drop. But if you under-correct, you are staring down escalating fraud loss mitigation costs and, eventually, regulatory scrutiny.

So the question is not “Do we add controls.” The question is “Which controls, where, and how do we make them smart.”

That is where digital identity verification becomes the backbone. Not just “did they log in,” but how are they behaving in session. Is the device familiar. Is the recipient new. Is the amount unusual. Is the pattern consistent with that customer. Identity authentication tools that combine behavioral analytics, session monitoring, and step-up verification can surface anomalies early enough to matter.

But I am also going to say something that I think we need to get comfortable with. Banks cannot solve this alone. Data sharing in banking matters. Fintech fraud risk is part of the chain. And law enforcement collaboration is necessary if we want to disrupt repeat actors and cross-border payment scams. If we keep treating this like each institution is its own island, scammers will keep exploiting the gaps between us.

I also touch on Nacha fraud trends because the ecosystem is connected. The rails differ, but the manipulation patterns repeat. And the more we share pattern intelligence, the faster we can respond across channels.

This episode is my strategic walkthrough of how push payment fraud is reshaping digital payment security and what a balanced payment fraud prevention strategy should look like in 2025.

What you’ll hear in this episode:

Why push payment fraud is escalating and why the $102 billion figure signals systemic stress.
How authorized push payment scams exploit customer trust in real time.
Why real-time payments fraud shrinks the intervention window and complicates recovery.
How Zelle fraud risk and RTP fraud exposure fit into broader peer-to-peer payment fraud patterns.
What digital identity verification needs to include beyond basic authentication.
How identity authentication tools can apply step-up controls without breaking user experience.
Why data sharing in banking and law enforcement collaboration are essential for payments ecosystem risk.
How a modern bank risk management strategy should approach fraud loss mitigation.

You should listen to this episode if you:

Oversee payments, fraud, or risk programs tied to push payment fraud and real-time payments fraud.
Are managing authorized push payment scams and rising APP fraud losses.
Are seeing Zelle fraud risk or RTP fraud exposure and need stronger digital payment security controls.
Are revisiting payment fraud prevention strategy and want a balanced approach to customer experience.
Want to improve digital identity verification and identity authentication tools without over-frictioning.
Need better data sharing in banking to address fintech fraud risk and cross-border payment scams.

Episode notes & key takeaways

The scale of push payment fraud is systemic

Let me just assure you, push payment fraud is no longer isolated to individual scams.

Losses exceeding $102 billion reflect systemic stress across rails and providers. APP fraud losses are affecting banks, fintechs, and customers at the same time. real-time payments fraud compresses detection windows because funds move instantly and can cascade across accounts quickly.

Institutions have to match speed with speed:

Real-time monitoring and escalation.
Faster intervention workflows.
Cleaner handoffs across teams when risk spikes.

Authorized transactions mask risk

authorized push payment scams bypass legacy unauthorized fraud logic.

The customer initiates the payment. Authentication succeeds. Traditional account takeover systems may not trigger. Detection shifts toward contextual and behavioral signals.

This is where digital identity verification needs to evolve:

Session behavior and navigation anomalies.
Device familiarity and login context.
New recipient risk and sudden payment changes.
Signals that align with manipulation, not credential theft.

Identity authentication tools have to support this shift if we want earlier interruption.

Balancing experience and control

Digital payment security is a strategy problem, not a single control problem.

Fast onboarding and minimal friction are competitive differentiators. But customer reimbursement pressure and scrutiny are rising. A thoughtful payment fraud prevention strategy applies friction selectively.

What selective friction can look like:

Real-time scam warnings at high-risk moments.
Step-up verification when risk signals align.
Transaction delay mechanisms for suspicious transfers.
Clear escalation paths for frontline and support teams.

The goal is fraud loss mitigation without broadly degrading experience.

Ecosystem collaboration is essential

push payment fraud is a payments ecosystem risk that crosses institutions and channels.

Banks, fintechs, telecom, and law enforcement each see different pieces of the chain. Data sharing in banking shortens response time. Nacha fraud trends can provide additional context across payment flows. Law enforcement collaboration helps connect repeat patterns and disrupt cross-border payment scams.

The reckoning is challenging, but it is clarifying. Institutions that invest in digital identity verification, smart controls, and ecosystem collaboration will be better positioned to protect customers and sustain digital payment growth.
