How to verify this certificate

This page is served directly from the Society of Professional Interpreters registry. A certificate is genuine only if its details match this page at this address; if it were revoked, this page would say so. The PDF carries a QR code that returns here. Each certificate is also sealed into an append-only integrity ledger, where every seal folds in the one before it, so the record cannot be quietly rewritten; this one is entry #1317, and the whole chain can be checked at /credential-ledger/verify.
