Issue Mill Test Report Credential

Cast-level signed credential for one Inconel 625 bar lot. Downstream forgers link to it automatically — the cast number becomes a live reference, not a re-typed field.

1Change any value below — or keep the defaults — and click Issue & Sign. Your browser signs the record with a demo key.

2Scan the QR with your phone (tap it to enlarge), or click Open verifier. The QR carries the signed record itself.

3On the verifier, try Tamper and Compare to paper. Back here, issue a correction to see how an honest typo is fixed.

Honest-mistake flow

A signed record is never modified. Pick the field that was wrong, enter the right value, give a reason — the mill signs version 2, which points at version 1. The QR doesn't change; the verifier shows the correction history in plain sight.
