Introduction: The last decade has seen rapid automation across factories in India and worldwide. Machines, production lines, and supply chains are increasingly data-driven, yet one critical element remains dependent on outdated tools: tracking people inside factory premises. While attendance systems and GPS can tell you who entered a site or where field teams are, they don’t reveal detailed, zone-level movement on the factory floor — and that blind spot affects productivity, quality, and safety.
Why Traditional Methods Are No Longer Enough
For years, factories used three main approaches to track workforce movement: GPS, RFID/swipe systems, and manual logbooks. Each approach has major limitations in modern industrial settings.
GPS Fails Indoors
GPS works outdoors for vehicles and field staff but is ineffective inside factories. Thick walls, metal structures, and heavy machinery block signals or produce large location errors (10–15 meters), making GPS useless for confirming visits to specific zones.
RFID and Swipe Systems Depend on Human Action
Swipe cards and RFID checkpoints require deliberate action. Cards can be shared, readers can fail, and maintenance costs add up. These systems do not provide continuous, automatic zone-level presence.
Manual Logbooks Are Error-Prone
Many plants still use manual logbooks for supervisor visits and checks. Logbooks waste time, invite errors, and can be manipulated. Managers often spend hours compiling reports based on incomplete or inaccurate entries.
Result: Missed checks, reduced accountability, wasted administrative hours, and a lack of real-time insights.
Why Focus on Inside-the-Premises Tracking
Many businesses already invest heavily in outside tracking — GPS for delivery fleets, field sales, and logistics. Those systems solve logistics problems, but they don’t improve factory-floor performance.
- Outside Tracking = Logistics Efficiency.
- Inside Tracking = Factory Performance, Quality, and Safety.
Attendance systems can show who entered a facility, but they cannot show whether a supervisor actually visited the QC zone or whether staff were present in packaging during peak hours. Zone-level visibility is the missing piece for better operational control.
How the Solution Works: BLE + Mobile App + Dashboard
The new generation of workforce tracking uses Bluetooth Low Energy (BLE) beacons combined with background mobile apps and a scalable backend with a manager dashboard. The solution provides continuous zone-level presence without manual action.
Key Components
- BLE Beacons: Small, battery-powered devices installed across production zones (e.g., Grinding, Blending, QC, Packaging). Typical detection range: 8–10 ft. Battery life: 3–4 years. Industrial grade (dust & humidity resistant).
- Supervisor Mobile App: Android/iOS app running in background. Detects beacons automatically and logs entry/exit and duration per zone without manual check-ins.
- Backend (Node.js + Express): Receives real-time events, stores secure time-series logs, and exposes APIs for reporting and integration with ERP/HRMS.
- Manager Dashboard (Angular/NextJS): Visualizes live movement, zone coverage, generates alerts, and produces downloadable reports (CSV/PDF).
This architecture delivers reliable indoor presence data where GPS cannot operate, enabling managers to act on accurate, timely information.
Key Benefits for Factories
- Zone-Wise Accountability: Every supervisor visit and duration is logged automatically — skipped zones are detected instantly.
- Operational Efficiency: Visibility into time distribution helps identify bottlenecks and optimize staffing.
- Safety & Compliance: Restricted zones can be monitored in real time and unauthorized access triggers alerts. Evacuation audits use last-known locations.
- Automated Attendance & Shift Reporting: Replace logbooks and punch cards with automated, instant reports.
- AI-Ready Analytics: Structured time-series data enables ML and Generative AI for anomaly detection, predictions, and natural-language reporting.
To maximize the value of real-time workforce tracking, many forward-looking manufacturers are now extending the data flow directly into their ERP systems. This integration ensures that zone-wise attendance, supervisor presence, and compliance checks automatically sync with production planning, payroll, and performance metrics. At Amar Infotech, we specialize in delivering IoT-enabled ERP development in India, enabling factories to combine the precision of BLE tracking with the intelligence of ERP analytics. Think of it as moving from “Where’s my supervisor?” to “How does his movement improve my bottom line?” — a question every smart factory wants answered.
Case Studies
Generic Case Study — Automotive Parts Manufacturer (Maharashtra)
A mid-sized automotive supplier faced inconsistent supervisor presence and missed QC checks. Manual logbooks were unreliable, and RFID solutions were too expensive to roll out across multiple units.
- Solution: Amar Infotech deployed BLE beacons in critical zones, installed a background supervisor app, and implemented a Node.js backend with a real-time dashboard.
- Outcome: Supervisor compliance improved from 55% to 100%, missed QC checks dropped by 90%, and daily reporting time reduced from 3 hours to instant automated reports.
Real Example — Shankar Masala
Shankar Masala, a fast-growing spice manufacturer in Baroda, improved supervisor accountability and reporting using BLE proximity tracking. Manual logs and GPS had failed to provide reliable zone-level presence.
