Digital Hallmark turns the heirloom in your jewelry box into a tamper-evident, scannable record. Every piece carries a tiny RFID tag fused into the metal, and the app reads it the same way airport-grade luggage tags work instantly, without batteries or wear. WHAT IT'S FOR Whether you're a long-time collector, just inherited a ring you can't quite explain, or you walked out of a boutique with a watch that came with a chip, Digital Hallmark gives you one place to keep its full story: when it was made, who hallmarked it, the appraisals it's gone through, the borders it's crossed, the people who've owned it before you. THE PASSPORT Tap a piece to your phone and you'll see its passport, a clean record of provenance, last appraisal, and ownership history. Every passport is anchored to a public, on-chain proof so a future buyer can verify it without an account, without trusting us, without trusting you. SCAN & VERIFY The Scan tab reads NFC tags on most modern iPhones and a wider class of UHF tags via an optional USB-C reader. Pass a piece in front of the phone; the app cross-references the read against the cryptographic anchor and tells you if it's the original chip, a clone, or a tag that's never been registered. Useful at pawn shops, estate sales, customs, and across that one cousin who keeps "borrowing" things. OWN THE WHOLE STORY Add voice memos to each piece , your grandmother's account of where the ring came from, the auction-house lot number, the receipt your spouse won't tell you about. Notes stay private, encrypted, and yours alone. PRIVACY-FIRST BY DEFAULT We don't track you across apps. We don't sell your data. We don't have ads. Authentication is handled by Clerk, payments are handled in Stripe's hosted portal (we never see card numbers), and you can delete your account in two taps from Profile → Delete account — the standard 30-day grace window applies, after which everything is permanently erased. WHO IT'S FOR - Collectors who want a portable record their insurance company will recognize - Heirs and estate executors trying to settle a jewelry box without a paper trail - Jewelers and wholesalers who need to authenticate batches at speed - Cross-border travelers carrying valuables under an ATA Carnet - Anyone who's ever asked "is this real?" - Anyone who's ever lost jewelry BUILT FOR YOU TO OWN Digital Hallmark is published by Digital Hallmark. We don't lock you in, you can export everything you've ever recorded at any time via Profile → Account → Export my data (GDPR Article 20). The on-chain anchors are public; if the app ever disappears, your provenance proof doesn't. Sign in with Apple or Google to get started. The app is free to use; advanced features for retailers and wholesalers come through an account upgrade. Questions?
