On-device passive liveness
MediaPipe blink and head-turn checks run on the phone before any pixel is uploaded — printed photos and static screens never get past the device.

Mobile attendance
Workers clock in by looking at the front camera — a true face recognition time clock. HelloTime runs MediaPipe liveness on the device, verifies the match against Azure Face API, and writes the clock event in under 1.2 seconds. It also works as an attendance app with selfie fallback, a manager-approval queue, PIN fallback, and a thumbnail-only retention policy that keeps India DPDP and EU GDPR teams happy.
The end-to-end Azure Face enrol and verify loop is rolling out to pilot customers while we finish wiring the backend endpoints — request a pilot slot.
Currently shipping to pilot customers. The same template will power the phone clock-in screen and the tablet kiosk on every site, so you enrol a worker once and they show up everywhere.
Enrol once, in three angles
At hire, the worker captures three reference angles from the front camera. Frames are sent to Azure Face API and stored as a PersonGroup template plus an encrypted thumbnail in Azure Blob — the raw photo is never retained on the device.
Look at the camera to clock in
The HelloTime mobile app opens the front camera in a circular viewfinder, with on-device MediaPipe liveness running before any frame leaves the phone. A single live frame is matched against the worker's template via Azure Face Verify.
Sub-second match, sub-1.2-second clock event
End-to-end latency target is under 1.2 seconds from tap to confirmed clock event, including geofence validation and idempotent server write. The kiosk path uses the same pipeline with a per-site PersonGroup cache for sub-second identification.
Anti-spoof escalation
If liveness fails or the match score falls below threshold, HelloTime forces a fresh selfie plus a manager-approval queue entry. Repeated failures escalate to PIN + selfie fallback so a clock event is never silently dropped on the worker.
Buddy-punching is the #1 deskless attendance fraud. HelloTime treats every borderline match as something a human, not the app, should resolve.
MediaPipe blink and head-turn checks run on the phone before any pixel is uploaded — printed photos and static screens never get past the device.
If a frame looks borderline, the app asks for a blink or a left-right head turn. This kills the printed-photo and looped-video replay attacks Truein customers complain about most.
Below-threshold matches are not silently approved. They land in a manager-review queue with the timestamped frame, so a human, not the app, breaks the tie.
PIN plus selfie keeps the day moving when lighting or hardware fail — no clock event is lost because a camera couldn't focus.
Truein owns the face-attendance category in India today. Here is how HelloTime is built to take it.
HelloTime pairs Azure Face Verify with on-device liveness to keep the full clock event under ~1.2s on a ₹15k Android tablet — Truein reviews on G2 routinely flag multi-second delays at shift start.
One PersonGroup serves the worker's phone clock-in and the site's tablet kiosk — no duplicate enrolment, no separate face DB. Truein's kiosk and mobile flows do not share a single recognition path.
Raw photos are never stored on the device. Templates live in Azure Face; thumbnails live in Azure Blob with Hot → Cool → Archive lifecycle tiering. India DPDP-aware from day one.
Face attendance is part of HelloTime's published Attend SKU. No sales call. Truein gates pricing behind a demo.
Face attendance is part of HelloTime's mobile-first attendance stack. It pairs with GPS geofencing and tablet kiosk mode so the same worker can clock in from a phone, a site tablet, or a manager's review screen — and end up on one timesheet, one approval, one payroll line.

A face recognition attendance system clocks workers in by matching a live face against an enrolled template. HelloTime uses on-device MediaPipe liveness, Azure Face Verify, and stores only a PersonGroup ID and encrypted thumbnail — never the raw photo.
Biometric attendance uses a biological marker to verify identity. Fingerprint readers scan a finger; a face recognition time clock scans the face. HelloTime's face-based biometric attendance software works on any Android or iOS phone with a front camera, so no dedicated fingerprint hardware is needed at the site.
Yes. HelloTime's kiosk mode runs on a sub-₹15k Android tablet. The same face template and anti-spoof liveness pipeline power both the phone app and the shared site tablet.
Selfie is a fallback, not the primary method. If liveness fails or the match score is low, the worker can clock in with PIN plus a timestamped selfie. The event goes to a manager-approval queue so the clock-in is never silently dropped.
HelloTime is designed for GDPR and India DPDP compliance. Raw photos are never stored on the device; only a PersonGroup ID and encrypted thumbnail are kept. Workers can request export or erasure, and deletion removes the template and thumbnail in one step. The feature is in pilot, so final compliance artifacts ship alongside general availability.
The end-to-end target is under 1.2 seconds from tap to confirmed clock event, including liveness, Azure Face Verify, geofence validation, and the idempotent server write. The kiosk path uses a per-site PersonGroup cache for sub-second identification.
HelloTime is built for India's deskless workforce: sub-₹15k tablet support, on-device liveness, no raw photo retention, and transparent pricing. The face recognition attendance system is currently in pilot; request a pilot slot to evaluate it.
Face attendance is included in the published Attend SKU. See the HelloTime pricing page for per-user pricing and trial terms.
