Tagging
A tool tracking system that combines BLE tags with GPS gateways so every drill, torque wrench, and instrument is accounted for at site check-in and check-out. Scope spans the tag firmware, the gateway hardware, and the asset register integration that ties it back to your inventory.
THE CHALLENGETools Walk Off Site and Nobody Knows When
On a busy job site or in a shared tool crib, a missing impact wrench or a calibration-overdue torque tool is rarely noticed until the moment it is needed. Paper sign-out sheets and barcode scans depend on someone remembering to scan, so the register drifts from reality within days. Tagging each tool with a BLE beacon and reading it automatically through fixed and mobile gateways closes that gap, so check-in and check-out happen without a manual scan and the asset register stays accurate.
Part of the Telematics and GPS Tracking stack, and commonly built alongside Asset Tracking Solutions.
WHAT'S INCLUDED
BLE Tags, GPS Gateways, and the Register Behind Them
BLE Tool Tags
Coin-cell and rechargeable BLE 5.x tags are designed around Nordic nRF52 silicon, with IP67 over-moulded housings that survive a tool crib and a dusty site. Advertising intervals are tuned for two to five year battery life, and each tag carries a tamper flag so a removed or destroyed tag raises an event rather than going silent.
GPS Gateway Readers
Each gateway pairs an ESP32 or STM32 BLE scanner with a Quectel EC200 or BG95 modem and a u-blox GNSS receiver. Fixed gateways watch gate lines and store rooms; ruggedised mobile gateways ride in vans and trailers so a tool box that leaves with a crew is tracked by location, not just last-seen.
Site Check-In and Check-Out
Raw tag reads are turned into clean custody events. When a tool crosses a gateway zone with a known operator badge it is checked out to that person, and when it returns it is checked back in. No queue at a scanner, no forgotten sign-out, just an audit trail of who held what and where.
Loss Prevention and Geofencing
Site boundaries and authorised zones are defined, then an alert fires the moment a tagged tool leaves without a matching check-out or sits idle past a threshold. Vehicle gateways report position over the modem so a tool box that drives off the wrong way is flagged in minutes, not at the end of the day.
Calibration and Maintenance Due
Calibration intervals and service due dates are attached to each asset record. The system warns before a torque wrench or pressure gauge falls out of calibration and can block check-out of an overdue instrument, so a tool that is no longer trustworthy does not reach a critical job.
Asset Register Integration
REST APIs and webhooks let custody events, locations, and calibration status flow into your existing asset register, ERP, or EAM system. Designed to map tag data into SAP and Maximo style registers, so the single source of truth stays where your team already works.
HOW YOUR TEAM USES IT
From Tool Crib to Job Site, Tracked Automatically
The value of a tool tracking system is felt at the counter and on the floor, not in a database. The workflow is designed so a store keeper, a site supervisor, and a maintenance planner each see exactly what they need without learning a new process.
Store Keeper View
A live list of what is in the crib, what is out, and who holds it. Issuing a tool is a walk through the gate line, not a manual log, and overdue returns surface at the top of the screen.
Site Supervisor View
A map of tagged equipment across the site with zone history, idle alerts, and a button to locate a specific tool by its last gateway read and BLE signal strength.
Maintenance Planner View
Calibration and service due dashboards with exportable records. Instruments approaching their interval are flagged before they expire, with full custody history for audit.
HOW IT WORKS
Tag, Gateway, Cloud
Tag Advertises
Each BLE tag broadcasts its identity and tamper state at a tuned interval. Signed advertising payloads keep a tag from being trivially cloned, and a motion sensor wakes the tag to a faster rate when the tool actually moves.
Gateway Reads and Locates
Fixed and mobile gateways scan, deduplicate, and timestamp reads, then attach GNSS position for mobile units. RSSI and zone logic decide whether a tag is inside, at a boundary, or gone, and the gateway buffers events when the cell link drops.
Cloud Resolves Custody
The backend ingests events over MQTT with TLS, matches them against operator badges and asset rules, and produces clean check-in and check-out records, loss alerts, and calibration warnings for the dashboards and your register.
STANDARDS AND ENGINEERING
Built to Survive the Crib and the Field
Rugged and Sealed
Tags and gateways are designed to IP67, with shock and vibration testing for tools that get dropped, thrown in a box, and rattled in a van. Enclosures are laid out in Altium and validated before tooling.
Secure by Design
BLE links use signed payloads, gateway to cloud runs MQTT over TLS, and provisioning uses per-device keys. Calibration and custody records are tamper-evident so the audit trail holds up.
Power and Reliability
Tag firmware on a FreeRTOS base manages duty cycling for multi-year coin-cell life, and gateways carry store-and-forward so a lost cellular link never means a lost custody event.
FAQ
Common Questions
How is BLE tagging better than barcode or RFID for tools?
Barcodes and passive RFID need someone to scan each item, so the register only reflects reality when a person remembers. BLE tags advertise on their own and the gateways read them automatically, so check-in and check-out happen as tools pass a gate line. BLE also gives you battery-backed motion sensing and range that a passive tag cannot.
How long do the tag batteries last?
Coin-cell tags are tuned for two to five years depending on the advertising interval and how often the tool moves. Motion-triggered tags stay quiet at rest and only speed up when the tool is actually in use, which is where most of the battery savings come from. Rechargeable tags are an option for high-value instruments.
Can the system track tools that leave the site in a vehicle?
Yes. Ruggedised mobile gateways with GNSS and a cellular modem ride in vans and trailers, so a tool box that travels with a crew is tracked by GPS position, not just by its last fixed-gateway read. If a tool leaves without a matching check-out, the system raises a loss alert with location.
How does calibration tracking work?
Each asset record carries a calibration interval and a service due date. The system warns before an instrument falls out of calibration and can block its check-out once overdue, so a torque wrench or gauge that is no longer trustworthy does not reach a critical job. Full calibration history is kept for audit.
Will this integrate with your existing asset register or ERP?
Yes. REST APIs and webhooks map custody, location, and calibration data into your asset register, ERP, or EAM system. Designed to integrate tag data into SAP and Maximo style registers, so your single source of truth stays where your team already works.
What happens if a tag is removed or destroyed?
Each tag carries a tamper flag and reports a removal or low-battery condition as an event rather than simply going silent. If a tag stops advertising unexpectedly, the system flags the asset for inspection so a stripped tag is treated as a loss-prevention signal.
