executive briefing
Backend truth. Device truth.
Backend truth tells you what reached the institution.
Device truth tells you what was true on the device when value moved.
YinkoShield establishes device truth and delivers it to the operator as evidence it can verify and use.
- Not a fraud product.
- Not a decision engine.
- Not a SaaS platform asking for control.
This is the role of Execution Evidence Infrastructure: reusable evidence for authentication, fraud, disputes, audit, operations, payments, and customer support.
the centralised decision model
"Send everything to us and we will decide."
the yinkoshield model
"We produce trustworthy device-side evidence. You keep control of the data, the policy, and the decision."
Fleet constraints remain. Decisions do not have to stay ambiguous.
Networks fail. Devices vary. Requests retry. Backends see fragments.
YinkoShield preserves the device-side context needed to decide through that ambiguity.
The operator's policy can act with cleaner evidence.
Six business outcomes — across authentication, fraud, disputes, operations, audit, and customer support.
-
Accept
Routine sensitive actions proceed with stronger ground truth than inference alone.
-
Step up
Friction is added when device-side evidence warrants it, not simply because the backend is uncertain.
-
Decline
Refusals become more defensible because they are backed by device-side evidence.
-
Queue
Ambiguous actions can be held for review instead of being blindly approved or declined.
-
Investigate
Fraud, operations, and forensic teams can reconstruct incidents with device-side evidence, not backend inference alone.
-
Support
Customer-service teams see what happened on the device, reducing dispute time and support ambiguity.
Device truth improves the economics of digital decisions.
-
Increase revenue
Trusted journeys can complete with less unnecessary friction, fewer avoidable step-ups, and fewer false declines.
-
Reduce cost
Shorten investigations, support cases, dispute handling, and operational reviews by giving teams device-side evidence instead of forcing them to reconstruct events manually.
-
Reduce loss
Reduce fraud loss by giving fraud and risk teams cleaner evidence when deciding whether to accept, step up, decline, queue, or investigate a sensitive action.
-
Reduce operational risk
Make decisions more explainable, auditable, and defensible.
The point is not another fraud score.
The point is better evidence at the moment decisions become expensive.
- Your stack stays.
- Your vendors stay.
- Your residency stays.
- Your decision stays.
YinkoShield composes with the existing environment instead of forcing a platform replacement.
- Your authentication provider stays.
- Your fraud model stays.
- Your AML pipeline stays.
- Your payment rails stay.
- Your dispute system stays.
- Your support tooling stays.
- Your telemetry stack stays.
YinkoShield is designed to support existing compliance and governance models rather than replace them.
- No transaction evidence needs to be sent to YinkoShield.
- The private signing key never leaves the device.
- Verification stays inside the operator's environment.
- Policy remains under the operator's control.
Verification stays inside your perimeter.
Evidence is generated on the device and verified by the operator against the public key it stores.
YinkoShield does not need to host the transaction, receive the evidence, or make the risk decision.
For regulated institutions, this matters: the trust architecture does not depend on a foreign vendor backend being available, reachable, or acting as the decision authority.
Digital value now moves through customer devices.
The backend remains critical, but many fraud, dispute, support, and operational questions now originate on the device: retries, replays, manipulated journeys, unstable networks, offline recovery, compromised runtimes, and ambiguous customer claims.
Across African banking markets, the direction is clear: digital-channel resilience, fraud controls, outsourcing risk, operational risk, and transaction integrity are becoming board-level concerns.
In South Africa, SABRIC reported that digital banking fraud remained the dominant fraud channel in 2024, accounting for 65.3% of reported incidents. Cases almost doubled from 31,612 in 2023 to 64,000 in 2024, while losses increased from R1 billion to over R1.4 billion.1
These attacks succeed because the backend cannot distinguish a user confirming under coercion or overlay manipulation from a user confirming normally. Device truth makes that distinction.
YinkoShield was designed for African mobile-banking operating conditions: heterogeneous Android fleets, POS and mPOS estates, unstable connectivity, offline-tolerant evidence generation, and high-volume digital channels. Not a generic cloud-fraud model retrofitted to African infrastructure realities.
Deployed in Tier-1 South African retail banking environments since 2019.
30M+ endpoints protected in production across mobile and payment estates.
Reference available on request.
The decision is whether the institution wants device truth as part of its digital operating model.
Not whether to replace fraud, authentication, compliance, payment, or support platforms. Three reversible steps.
-
stage 01
