ZeroKey is trusted across a wide range of industries.
Alaska Oil Drilling Platform
Enhancing personnel safety and location awareness with ZeroKey’s 3D virtual fencing.
By equipping staff with ZeroKey tags, we can track their movements with centimeter‑level precision and monitor three‑dimensional hazard zones—including vertical space—in real time. As operational risks shift daily, such as during well openings or work at height, virtual fences can be reconfigured instantly through software updates without stopping on‑site activities. This has significantly reduced patrol workloads and near‑miss incidents.
Automotive Manufacturing Plant
Leveraging ZeroKey for precise AMR localization and control on fully automated production lines.
In a fully automated automotive production line, ZeroKey’s QuantumRTLS is used to achieve highly accurate AMR localization and control. By operating without physical guide paths, the facility has realized a compact and efficient multi‑model mixed production line with completely free‑navigation AMRs.
Logistics Warehouse
By capturing storage locations in three dimensions, operational efficiency doubled and annual costs were reduced by over ¥65 million.
By using scanners equipped with ZeroKey, the system automatically captures the 3D coordinates of each item. Displaying both worker and item locations in real time on tablets enables optimized picking routes. As a result, operational efficiency increased, labor costs were reduced, and training time was compressed to one‑sixth, leading to significant improvements across the entire warehouse supply chain.
ZeroKey
ZeroKey Inc. (hereafter, “ZeroKey”) offers ZEROKEY, a high‑precision indoor positioning system that uses ultrasonic sensors to provide accurate three‑dimensional localization even within large indoor spaces.
Common indoor positioning methods such as UWB, Bluetooth, Wi‑Fi, and RFID
require complex calibration and can only provide two‑dimensional coordinate
information.
ZeroKey’s high‑precision indoor positioning system (U.S.
patented) leverages proprietary ultrasonic technology to create a GPS‑like
architecture using ultrasound. This enables true three‑dimensional (X, Y, Z)
spatial localization and delivers centimeter‑level positioning accuracy.
In addition, ZeroKey’s proprietary calibration technology enables much faster
device installation, system tuning, and startup compared to conventional
methods.
By combining our technical support capabilities with ZeroKey’s
technological expertise, we provide end‑to‑end assistance—from device placement
design to operational deployment—tailored to each customer’s requirements and
environment.
Why can ZeroKey achieve high‑precision indoor positioning?
Proprietary Ultrasonic Technology
By leveraging its U.S.-patented proprietary ultrasonic technology, ZeroKey achieves centimeter‑level high‑precision positioning.
A World‑Leading High‑Precision Indoor Positioning Device
ZeroKey delivers more than ten times the accuracy of UWB, and over one hundred times the accuracy of BLE or Wi‑Fi in indoor positioning. It also enables the acquisition of full 3D (X, Y, Z) coordinate data—capabilities that conventional technologies have been unable to achieve.
A Calibration Tool That Requires No Detailed Surveying (Automatic Coordinate Recognition)
Using the ZEROKEY tool, automatic calibration is performed, enabling 3D spatial visualization and distance measurement without the need for prior precision surveying.
Compliance with Japan’s Radio Law Technical Standards
All models distributed in Japan are certified for technical compliance under Japan’s Radio Law. No special application is required after purchase, allowing immediate use.

How ZeroKey Solves Key Challenges With spatial recognition technology that delivers a level of precision unattainable by conventional indoor positioning systems, ZeroKey solves key challenges faced in factories, logistics warehouses, and other indoor environments.
Setting No‑Entry Zones as 3D Virtual Fences
Hazard zones are defined as 3D virtual fences that include not only horizontal areas but also vertical space, triggering alerts the moment a breach occurs. Layout changes on the shop floor can be accommodated flexibly through software updates alone.
Prevent collisions between workers and vehicles
ZeroKey monitors the distance between worker tags and vehicle tags in
millisecond intervals.
When they come too close, the system issues
warnings through lights, buzzers, and vibration, while simultaneously
notifying the management system—preventing near‑miss incidents before they
occur.
Optimize workflow routes and equipment layout through movement analysis
ZeroKey quantifies worker movement patterns, enabling data‑driven identification of improvement points and smooth redesign of workflows and equipment layouts. This eliminates reliance on individual intuition and supports objective, scalable process improvement.
Provide real‑time guidance for complex assembly operations
ZeroKey detects the operator’s hand movements and provides real‑time guidance on the next step and required parts. This prevents omissions and procedural errors during assembly, ensuring consistent work quality.
Improve efficiency in picking operations and parts management
ZeroKey’s 3D positioning accurately identifies both the location and shelf height of inventory. By displaying the shortest picking route on handheld devices, it optimizes picking workflows, reduces mis‑picks, significantly shortens task time, and boosts overall warehouse productivity.
Accurately measure screw and bolt tightening
ZeroKey tags mounted on tools record screw‑tightening positions and
timestamps with millimeter‑level precision.
Any deviations from the
required torque or sequence are detected instantly, and work records are
generated automatically.
This eliminates paper‑based documentation and
ensures robust quality traceability.

FAQ
- Q
- What is the measurable distance or coverage range?
- A
- The maximum measurable distance between a mobile tag and an anchor is up to 20 meters. When anchor nodes are installed on the ceiling—typically 7 to 10 meters high in factories or warehouses—the system can accurately measure objects located on the floor within that indoor space. In addition, the standard coverage area scales with the square of the number of anchor nodes, meaning that 10 anchors cover approximately 100 m², 20 anchors cover about 400 m², and 50 anchors enable positioning across roughly 2,500 m².
- Q
- Does temperature, humidity, or airflow affect positioning accuracy?
- A
- Temperature can affect positioning accuracy, so each device is equipped with a built‑in temperature sensor that allows for automatic compensation. Humidity has very little impact on performance. However, in situations where strong airflow is directed at the device, ultrasonic reception may be affected, so this should be taken into consideration when designing the installation layout.
- Q
- Why does ZeroKey achieve higher accuracy than UWB and other positioning technologies?
- A
- UWB and BLE, as well as other indoor positioning technologies, estimate location using radio waves through methods such as Angle of Arrival (AoA), which relies on signal strength and angle, and Time Difference of Arrival (TDoA), which uses the signal’s arrival time. However, because radio waves travel extremely fast, differences in arrival time become very small at indoor distances, making it difficult to achieve high accuracy.
- Q
- Does the system operate as a standalone solution?
- A
- Yes. All software required for ZeroKey’s indoor positioning system is built into the Edge Computing Device (ECD), allowing it to operate without the need for communication with any external servers. The positioning data generated by the system can be accessed on the user side through the ECD’s API.
- Q
- How long does the system operate on a full charge?
- A
- The power consumption varies depending on the positioning frequency settings. The universal mobile device operates for 2 to 3 days on a full charge, while the wristband‑type device lasts for 1 to 2 days. The button‑cell model has a significantly limited positioning frequency but can operate for approximately six months. For anchor nodes, the PoE type is continuously powered and therefore does not contain a battery, whereas the universal‑type anchor node offers an operating time similar to the mobile device, at 2 to 3 days on a full charge.
