Decode EMV.
Find the Root Cause.
EMVAgent helps payment teams decode TLV data, analyze transaction declines, and identify the most likely root cause across terminal, acquirer, issuer, and network flows. Turn raw EMV tags into structured diagnostics and clear next actions.
From raw data to root cause
in three steps
Paste EMV data or describe the decline
Drop in TLV data, tag values, TVR bytes, issuer data, or simply describe what happened. No pre-formatting required.
AI multi-agent analysis
EMVAgent parses the data and runs specialized diagnostics across EMV logic, CVM flow, terminal behavior, and authorization path.
Get structured root cause and fix recommendation
Receive a clear summary of the issue, the likely responsible party, and the next action to test or remediate.
Built for every layer
of the payment stack
Whether you’re an issuer, acquirer, terminal maker, or network operator — EMVAgent speaks your language.
Banks & Issuers
Investigate decline patterns faster, understand issuer-side decision signals, and reduce time spent on complex EMV support cases.
Acquirers & Processors
Identify terminal, routing, configuration, and EMV data issues before they become repeated production problems.
POS Terminal Manufacturers
Accelerate certification, support, and troubleshooting by turning low-level EMV data into readable diagnostics.
National Switches & Networks
Support ecosystem participants with faster issue triage, clearer root-cause visibility, and more consistent EMV interpretation.
Built to be checked,
not just trusted
Every answer is something your team can verify — grounded in the EMV spec and tuned by people who work with it every day.
Tuned with EMV experts
Outputs were reviewed and corrected by specialists who work with EMV every day, not left to a model on its own.
Grounded in the spec
Every diagnosis points to the tag and the EMV rule behind it, so your team can check the reasoning, not just take it on faith.
Consistent
The same input gives the same answer, so two analysts looking at one case reach the same conclusion.
Always-on diagnostics,
backed by real experts
For banks, acquirers, and switches that want failed transactions handled automatically — with people behind the AI when it matters.
Failed transactions come in automatically
Failed EMV transactions flow into the service on their own. The AI reviews each one and writes a clear opinion on what likely went wrong and what to do next.
Your team decides
Your experts read the opinions and act on them. If an answer does not look right, they send it back to us.
We close the loop
If the AI was right, we reply with a full explanation so your team can act with confidence. If your expert was right, we update the AI so it gets better over time.
Fair billing. If the issue was on our side, we do not charge for that work. You only pay for the extra analysis you ask us for.
