Replace trust in unverifiable COAs and forwarded PDFs with checkable, issuer-signed evidence.
The permanent reference
A TECRID—Test Evidence Credential Record Identifier—is a persistent identifier and verification record for laboratory reports, with access governed by the record’s disclosure settings.
Issuer signature required · Versions preserved · Visibility controlled
Free core trust. Commercial value through VLE QUALIFIED and HMTc certification.

The proof problem · Free core trust
Counsel and retailers waste time reconciling folders of PDFs: tracing the issuer, matching the lot, and finding the latest correction. That discovery friction follows every handoff. Give them one checkable, issuer-signed evidence record to resolve.
Think of a DOI analogue for lab reports: a persistent identifier that leads back to the record. TECRID adds issuer-signature checks, current status, and version history. It is not a DOI or a certification.
Core issuance and verification are free. Private evidence stays subject to its disclosure controls; paying never buys issuer credibility.
Join TECRID freeVLE uses TECRID-linked evidence to assess whether a specific lot is QUALIFIED. The commercial opportunity follows qualification, as an eligible lot moves toward reserve.
Qualification is not for sale. VLE currently operates as a demo and pilot; TECRID does not promise a qualified lot or a transaction.

Fees pay for certification work. A TECRID authenticates the evidence; it does not award certification or guarantee a passing result.
Apply for HMTc certificationAuthenticity has a clear boundary. TECRID does not certify products or safety and does not replace ISO/IEC 17025 accreditation, representative sampling, or expert interpretation. Commercial value belongs in downstream VLE activity and HMTc certification; core trust stays free.
How a TECRID works
The laboratory creates the signed evidence record. TECRID verifies and preserves it. Authorized recipients resolve the same source instead of reconciling separate PDFs.
What is a TECRID? →Results, methods, sample identifiers, dates, units, and source-document fingerprints are recorded directly from the issuing laboratory.
The API verifies the laboratory’s Ed25519 signature against its reviewed key, assigns the TECRID, and preserves the version fingerprint.
Brands, certifiers, retailers, regulators, and the public see only the record and fields they are authorized to receive.
Who TECRID serves
TECRID reduces repeated document handling without pretending that every participant needs the same view or authority.
Give customers a signed record they can reuse, so your team spends less time confirming PDFs. As buyers request TECRID-linked evidence, your laboratory gains a path to more testing of independently sealed samples. Pilots must establish the volume gained.
For laboratories →Brands & suppliersOrganize laboratory evidence by SKU and lot, review trends, and control who receives private findings.
For brands →Counsel, certifiers & retailersReduce discovery friction: resolve the issuer, lot, current status, and correction history from one scoped record.
For evidence recipients →Technology teamsCanonicalize, sign, issue, resolve, route, and monitor evidence through the implemented API.

Which registered laboratory signed a record, what that record contained at issuance, its current status, and its visible amendment history. A PDF or COA alone is not a TECRID.
A record may be private, recipient-controlled, or public. A TECRID cannot be compelled into public visibility by another participant.
It does not replace ISO/IEC 17025 accreditation, representative sampling, sound analytical methods, regulatory judgment, or expert interpretation.

Verification and the controlled pilot are free. Public issuance begins only after identity, scope, key-control, and conformance gates pass.
