Digital Hallmark turns the heirloom in your jewelry box into a tamper-evident, scannable record. A tiny Digital Hallmark chip fused into the metal links each piece to its passport โ€” read in an instant, with no batteries and no wear. WHAT IT'S FOR Whether you're a long-time collector, just inherited a ring you can't quite explain, or walked out of a boutique with a piece that came with a chip, Digital Hallmark gives you one place to keep its full story: photos and video, appraisals and certificates, where it came from, and everyone who has owned it. THE PASSPORT Open a piece to see its passport โ€” a clean record of provenance, appraisals and ownership history. Chipped pieces are anchored with a public on-chain proof, so a future buyer can verify them independently. Share a public passport link, or keep any piece completely private. SCAN & VERIFY Connect an optional Digital Hallmark UHF reader and scan a piece to confirm it is the original chip, a clone, or a chip that has never been registered. Useful at estate sales, when buying pre-owned, or anywhere you need to ask "is this real?" TRANSFER & PROTECT Transfer ownership securely when you sell or gift a piece, or request ownership of a piece you've scanned. Report a piece lost or stolen and get alerted with the time and place if anyone scans it. OWN THE WHOLE STORY Add photos, video, voice memos, documents and up to three links to each piece โ€” your grandmother's account of where the ring came from, the auction lot number, the receipt. Search finds pieces by their notes and attached documents too. PLANS Start free for your first year. Optional subscription plans โ€” Beginner, Vault, Collector and High Net Worth โ€” add more pieces, chipped pieces and storage, collections, full history and the AI assistant. Subscriptions are billed through your Apple ID, renew automatically unless cancelled at least 24 hours before the end of the period, and can be managed or cancelled anytime in your App Store account settings.
