TapDPP public betas land on Android and iPhone — anyone with an NFC tag can now try a spatiotemporal DPP

MONTRÉAL, June 5, 2026 — QDat.io, a brand of Meerv Inc., announces public betas of TapDPP for both Android and iPhone. Both clients are available for download from QDat.io/tapdpp — the Android build as a sideloadable APK, the native iPhone build through Apple's TestFlight — and both interwork fully with the tapdpp.qdat.io playground, so anyone with an NFC tag can experiment with spatiotemporal Digital Product Passports (SDPP) hands-on.

An SDPP doesn't resolve a tag URL by the requester's IP. It resolves on (When, What, Where) — the moment a tag was tapped, the on-tag identity, and the reader's position — and serves a different view accordingly. TapDPP is the simplest way to see that work: write the canonical https://tapdpp.qdat.io/<UID> URL onto a tag, tap it back, and the playground answers from the When/What/Where of that read. The same tag can resolve to a consumer view at home, a service-history view at a repair shop, or an alternate URL inside a geotime fence — decided server-side, not on the tag.

Android + iPhone — public beta

TapDPP — Android v1.22.0 · iOS public beta

Tap to open QDat.io/tapdpp — download both betas, see the seven-tap walkthrough, and watch the playground resolve a real tag URL.

TapDPP turns any NFC-equipped Android phone or tablet — and now any recent iPhone — into a fully-paired QDat.io reader. It writes the canonical DPP URL onto NFC Type V (ISO 15693) and NFC Type A (NTAG / Mifare Ultralight) tags, publishes every tap live to the QDat.io MQTT broker, and queues scans in an encrypted offline cache when the broker is unreachable. Both betas share the same MQTT wire format and write the same tag URL, so a tag written on Android reads identically on iPhone — and vice versa.

The companion playground, tapdpp.qdat.io, runs the exact same QDat.io codebase an operator would self-host, kept publicly online so the loop closes end-to-end. To try it on your own phone and your own NFC tag, get TapDPP from QDat.io/tapdpp, request demo credentials from the /demo form, sign in to tapdpp.qdat.io, and follow the seven-tap walkthrough — from install to a server-rewritten tag URL in under five minutes. For a private, on-premise deployment of the DPP module inside your own perimeter, book a deployment demo.
