The smartphone app problem.
Workers may not have or carry a smartphone on shift. When they do, they usually forget to start and stop sessions through a long day. The evidence goes missing.
Continuous Human Activity Recognition Module
Did the work actually get done?
CHARM™ Band turns each shift into a verifiable record automatically. No smartphone. No QR codes. No supervisor guesswork.
- On-the-wrist
- No worker app required
- Sensor-driven
- Activity patterns, not memory
- Evidence layer
- Built to integrate
The field reality
The field breaks human-dependent systems.
The QR code problem.
QR check-ins are easy to separate from the work itself. A code can be shared, moved, or scanned once while the actual task remains unverified.
The supervisor digigence problem.
Manual logs rely on memory, judgment, and pressure at the end of a shift. That is not a defensible record when clients ask what happened.
The CHARM™ approach
Evidence that doesn't depend on what anyone remembers to do.
The CHARM™ Band is a sensor-grade wristband worn through the shift. Embedded motion sensors recognise activity patterns such as walking, mopping, vacuuming, scrubbing, and standing idle.
Pair it at shift start. Return it at shift end. The output is a verifiable shift narrative: where work happened, what activity was recognised, and for how long.
There is no app for the worker. Nothing to start. Nothing to stop. Nothing to remember.

Three steps
From shift start to verifiable record.
-
1
Pair.
Worker taps their ID card and receives a CHARM™ Band for the day.
-
2
Wear.
The shift runs as normal while the band recognises activity in the background.
-
3
Return.
The band returns to the station. The shift narrative is ready for review.
