Unique identifier
A persistent Certificate ID and seal serial number link the physical seal to its digital record and prevent reuse or duplication.
A Security Seal Certificate creates an auditable record that documents custody transfers, deters tampering, and helps demonstrate chain-of-custody in regulatory or contractual disputes.
Each party’s responsibilities should be defined in policy and recorded on the certificate to reduce disputes and ensure clear attribution.
A supervisor signs to confirm seal placement and condition at the point of dispatch. The signature should include title, contact, and a unique verifier ID to link the signer to the audit trail.
The receiving agent signs to acknowledge receipt and any observed discrepancies. Their signature confirms transfer of custody and is part of the documented chain of custody.

| Audit capture | Record IP, timestamp, and signer metadata |
Choose a solution that records signer attribution, stores tamper-evident copies, and supports the integrations used in your operational stack.
A persistent Certificate ID and seal serial number link the physical seal to its digital record and prevent reuse or duplication.
Signed entries must include full name, role, and authentication evidence to support attribution under ESIGN (15 U.S.C. ch. 96) and UETA.
Describe seal condition and include photographic or barcode evidence where available for later verification.
An immutable log of actions, timestamps, IP addresses, and attachments verifies the sequence of custody events.
When required, include a notary acknowledgment or RON session record to augment evidentiary weight.
Indicate where the signed certificate is stored and the retention period required by policy or regulation.
Provide signed copies in PDF/A and standard PDF to ensure long-term readability and forensic compatibility with verification tools.
Restrict editing and enforce role-based access; record permission changes in the audit trail to protect integrity.
Embed or attach a verification token or QR code that resolves to the audit record to simplify later authenticity checks.
Store signed files with tamper-evident hashing and record cryptographic checksums to detect unauthorized changes.
Prepare and sign the certificate when the seal is applied.
Deliver the certificate to regulators or contract parties when requested.
Retain RON audio–video sessions per state rules, typically 5–10 years.
Report suspected tampering per internal SLA timelines and regulator requirements.
Keep records accessible for the initial audit window required by applicable regulators.
Complete all identification and contextual fields before verification.
Authenticate signers and capture proof of identity and consent.
Apply the physical or electronic seal and record serial numbers and images.
Store signed copies and audit trails in a controlled, tamper-evident repository.
Optica automated seal records for inventory control and custody verification.
A small real estate firm digitized seal certificates for property transfers.
