Enter the item number from your verification card — it's next to the QR code. You'll see the item's permanent record: photos, weight, instrument readings and the full audit trail — and you can re-run the cryptographic proof yourself, right in your browser.
Scammers can print QR codes pointing at lookalike sites. Genuine Metal Stack records live only at metalstack.app. Anywhere else — treat as unverified.
A record is only as good as the match. Compare the item in hand against the record's photos and the weight to 0.01 g — and check the tamper hologram is intact. A peeled, lifted or damaged hologram means the seal is void.
