Understanding Passive RFID
SCAN~LINK's Core Technology
Passive RFID is the technology behind SCAN~LINK's worker detection systems. In SCAN~LINK's Armour System™, Passive RFID is a detection technology that identifies tagged workers near heavy equipment without requiring batteries or charging. Passive tags are powered remotely by the Antenna itself, making them lower-maintenance and more durable in harsh jobsite conditions. SCAN~LINK uses passive RFID to detect people specifically (not just objects or motion), helping prevent struck-by accidents across mining, construction, forestry, oil & gas, waste, and industrial sites.
Why Understanding this Technology Matters
HOW IT WORKS — STEP BY STEP
SCAN~LINK keeps it simple. Groundworkers are tagged with passive RFID tags in their vests or hard hats, while equipment is outfitted with an antenna and in-cab display. Everything communicates wirelessly for fast, hassle-free installation on all equipment types. No extra bulk, no charging, and no maintenance.
Our streamlined approach incorporates passive RFID tags directly into PPE that workers are already required to wear. This makes the Armour System effortless to adopt. No extra steps for workers and no additional gear to manage.
When a worker wearing tagged apparel enters the danger zone behind a machine, the operator is immediately alerted with both audio and visual prompts from the in-cab display unit. At the same time, an external alarm is activated to warn the groundworker, ensuring both parties are aware of the hazard.
Passive RFID Marker Tags can also be applied to fixed assets like generators, wellheads, or structures. Unlike other systems that detect objects indiscriminately or require daily checks, SCAN~LINK detects only what you choose. That means zero false alarms, less operator workload, and faster, safer responses to real threats.
WHY PASSIVE RFID?
Passive RFID technology provides unique benefits for improving worker safety and preventing struck-by incidents around heavy equipment. Passive RFID tags require no batteries or maintenance and are designed to last 20+ years. It enables consistent and reliable detection of personnel in hazardous areas while generating actionable safety data and analytics. This helps identify high-risk areas, reveal operational trends, and support long-term improvements in jobsite safety performance.
NO BATTERIES OR MAINTENANCE
Passive RFID tags require no batteries or charging, meaning they are maintenance-free once installed. This ensures consistent operation without ongoing upkeep on the worker side.
NO FALSE ALARMS
SCAN~LINK strictly detects only tagged workers or assets. Each tag provides a unique ID that can be associated to any worker or asset for data management, enabling clear, consistent detection of personnel in high-risk zones and supporting accurate safety data.
ACTIONABLE SAFETY INSIGHTS
Detection data provides visibility into where interactions between workers and equipment occur, helping identify high-risk areas and recurring patterns. This supports data-driven improvements to jobsite safety over time.
