TAMREVS
Temporary Anonymous Multi-Factor Retail Exit Verification System
Retail exit verification, without identifying the customer.Verify the journey, not the identity.
TAMREVS is a privacy-first retail loss-prevention system designed to verify that the person leaving a store is associated with the same temporary session created when they entered. It is intended to give retailers a new way to address exit theft without relying on permanent customer identities, while keeping the underlying verification architecture proprietary.

Proprietary technology & intellectual property
TAMREVS is proprietary technology developed by Simon Mowatt.
Patent protection has been sought for the TAMREVS system architecture, including eight claims directed towards core aspects of the system and its operation.
The material presented on this website provides a high-level overview for evaluation and discussion purposes only. The underlying architecture, methodologies and implementation are proprietary.
TAMREVS is not an open-source concept.
Interested in the technology? We welcome discussions with organisations operating in retail loss prevention, security, verification and related fields.
The problem
Retail shrinkage is a multi-billion-pound epidemic. Existing tools are stuck in trade-offs.
Every current approach sacrifices something fundamental: accuracy, privacy, throughput, or cost.
Electronic article surveillance
Requires every product to be tagged. Misses untagged items and bulk theft.
CCTV
Mostly retrospective. It records the crime rather than preventing the exit.
Security guards
Effective but expensive, inconsistent, and hard to scale across thousands of stores.
Receipt checks
Inconvenience every legitimate customer and still rely on human judgement.
Facial recognition
Permanent biometric databases create privacy, regulatory, and public-trust risks.
Single-signal AI
A single source of information can create uncertainty and operational trade-offs.
The journey
Three beats. No friction.
Entry, shopping, exit. The system only does what it needs to do, only when it needs to do it.
Entry
A temporary privacy-preserving session begins without requiring a permanent customer identity.
Shopping
Relevant context can be associated with the temporary session while the customer shops normally.
Exit
The temporary session is reconciled at exit and an operational result is produced.
Privacy by design
What TAMREVS never collects
The system is deliberately built to need as little as possible.
What exists, briefly
Temporary encrypted sessions
Relevant information is associated with a temporary session, used to support an operational confidence result, and securely deleted after exit.
Operational model
Clear when possible. Review when necessary.
TAMREVS is designed to support an operational result without requiring a permanent customer identity. Where the available information is not sufficiently clear, the process can defer to staff.
Operational result
The available context supports a clear operational outcome at the point of exit.
Staff review
Where the result is not sufficiently clear, staff remain in the loop rather than relying on an uncertain automated outcome.
The dossier
Four pillars, one method.
The full reference architecture spans thirty-five chapters. These are the four routes through it.
Verification
The session lifecycle and decision framework that turns available information into an explainable operational recommendation.
Governance
Privacy by design, human oversight, fairness testing and the controls that keep the platform accountable.
Evidence
Prototype objectives, pilot phases, governance gates and the measures that decide whether the concept progresses.
Honesty
Assumptions, known limitations and open questions, stated plainly. Nothing here has been validated yet.
