The QDat.io data plane
One trusted plane from edge devices to executive dashboards.
- ▸Capture Layer — secure connectors for sensors, ERP feeds, RFID/NFC scans, and operator events, with edge-to-cloud ingestion, automatic schema detection, and buffered delivery so nothing is lost when a device goes offline.
- ▸Verification Layer — time-stamped validation rules, confidence scoring, and tamper-evident records. Every event is cryptographically signed and stored in an immutable audit log.
- ▸Action Layer — trigger workflows, alerts, and API callbacks when thresholds or anomalies are detected, closing the loop between the physical world and downstream systems.
- ▸Spatiotemporal storage — every reading carries time and place, so you can query what happened, where, and when across the whole fleet.
QDatDroid
The Android field client that turns a phone or handheld into an RFID/NFC reader.
- ▸Provision a device against a cluster in a single scan: licence, MQTT broker credentials, and the device's command/response/data topics arrive together.
- ▸Reads UHF RFID (Zebra readers) and NFC tags (type A / type V), arms OPUS temperature dataloggers, and streams readings live over MQTT.
- ▸Built-in licence lifecycle: request a trial, validate on launch, sync usage, renew, or revoke — all from the device.
- ▸Writes a Digital Product Passport URL directly onto provisioned tags, so a public scan resolves to your branded page.
Cooldat® & CoolTag
Cold-chain temperature intelligence on a passive tag.
- ▸Continuous temperature history captured on the tag and reconciled into the QDat.io plane on every read.
- ▸Predictive shelf-life and excursion detection — see not just the current reading but where a product is headed.
- ▸CoolTag passive sensing with no battery to manage at the item level; Cooldat dashboards aggregate fleet-wide condition.
- ▸Montréal-grade jitter-tolerant ingestion: phone-tethered reads with no GPS still record cleanly instead of failing the batch.
Heli & SDPP
Field-ops tooling and the Spatiotemporal Digital Product Passport.
- ▸Heli.app — a companion field client in the QDat.io family for guided capture and provisioning.
- ▸Digital Product Passport (DPP) — public, no-auth pages at https://<dpp-host>/<id> rendering operator-authored HERO / IDENTITY / SPECS / LOCATION / PROVENANCE / DOCUMENTS / MATERIALS / CONTACT / QR sections.
- ▸Passport templates — branding, ordered sections, a closed field allowlist (adding a column never auto-leaks it), and auto-bind matchers so new tags inherit the right template automatically.
- ▸DPP rules engine — geofence + time (spatiotemporal AND) rewrite rules that redirect a visitor based on where and when a tag is scanned.
