Deterministic embedded devices designed to emit check-in and check-out events over the network, acting as a reliable physical source of attendance data for external systems.
A compact embedded device designed to emit attendance events at the moment they occur. The device does not store historical data and does not expose local logs.
Events are transmitted over the network to a central backend, where timestamps are assigned at write time.
A backend component responsible for receiving, timestamping and storing attendance events transmitted by devices.
The backend exposes events through simple network interfaces, allowing integration with existing systems without coupling business logic to the edge device.
This system is designed for developers and system integrators who require a predictable physical source of attendance events without embedding application logic into hardware.
Devices act as network-based event emitters. All interpretation, validation and processing of events is intentionally delegated to external systems.
You consume the events. You define the semantics.
Design rationale: network-based event emitter
The system is used in environments where attendance events must be collected reliably and made available centrally, without manual data handling.
It provides raw, verifiable event data intended to be consumed by existing software and operational workflows.
We design technical components for emitting and transmitting attendance events.
We do not define HR rules, calculate payroll, manage shifts or interpret labor regulations.
The system intentionally limits its scope to event acquisition and transmission.
Local data storage on edge devices
Manual retrieval of attendance logs
Implicit assumptions embedded in hardware
Tight coupling between data collection and processing
Mobile teams and temporary setups where attendance events must be captured without on-site data consolidation.
Geographically distributed teams requiring centralized access to attendance events without visiting each location.
Dynamic environments where local data extraction would introduce delays and operational overhead.
