01 CONTEXT & DELIVERY 

## The whole product.

Grupo Enge10 ran on spreadsheets, a time clock that did not speak to finance, and tool control done on paper. Sistenor is the platform that replaced all of it: seven systems sharing one registry of companies, sites, workers and suppliers, behind a single sign-in. Finance owns the central registry and the others read from it. People on site use the tool crib tablet or the time clock app; people in the office use finance and engineering. Identity is shared, so removing somebody cuts access to every system at once.

### Solution scope

Finance and the central registry, REP-P time clock with face recognition, workplace safety, an RFID tool crib read from a tablet, site diary and contracts, all under a single identity.

02 FEATURES 

## How it works in practice.

Capabilities connecting the user experience to operational needs.

01 

### One central registry

Companies, sites, workers and suppliers live in one place. The other systems read from it, and nobody types the same record twice.

02 

### REP-P time clock

Clock-in from the phone and from an installable app, with face recognition, inside the REP-P rules.

03 

### RFID tool crib

A cabinet driven by a PLC with RFID reading, operated from a tablet, with the management panel alongside and per-worker authorisation.

04 

### Workplace safety

Work fronts, hazards, corrective actions and safety standards tracked per site.

05 

### Site diary and contracts

Daily reports and contracts tied to the same sites finance uses, with no parallel spreadsheet.

06 

### One account for everything

A single identity across all seven systems. Same password everywhere, and offboarding happens in one place.

03 ARCHITECTURE & TECHNOLOGY 

## Behind the interface.

Sete sistemas independentes sobre um cadastro comum e identidade única

Each system has its own repository, deployment and cadence, and all of them lean on the same registry schema and the same identity provider. Face recognition is a shared library between the time clock and the tool crib rather than two implementations. The cabinet has its own microcontroller firmware and an agent that talks to the tablet.
