Sentinel Blade – Long-Life BLE Tracking Card + Platform Access

The Sentinel Blade is a long-life, reinforced BLE tracking card engineered for applications requiring slim, rugged hardware with dependable proximity intelligence. Constructed using a tempered-glass front and an anodized aerospace-grade aluminium frame, the Blade provides increased durability and structural rigidity, making it suitable for demanding operational, commercial, and personal environments. 
 
Powered by a 540 mAh disposable battery, the Blade delivers up to 24 months of operational life with zero charging or maintenance during its primary battery cycle. Throughout this period, the Blade connects through the global BLE crowdsourced detection method, enabling proximity awareness, movement insights, and last-seen visibility without relying on GPS, SIM cards, or cellular networks. 
 
An integrated audible buzzer supports rapid on-site recovery, assisting users in locating misplaced items in crowded or confined spaces. The Blade’s card-like profile makes it ideal for storage within document holders, protective cases, operational kits, or compact gear bags. 
 
Platform access is included for the duration of the original/supplied battery lifespan only. During this period, users benefit from proactive device management including geofence violations, movement alerts, historic trips for 6-months, event history, and device health monitoring. Unlike reactive services such as Apple “Find My” or Google “Find My Device,” which rely solely on last-known positions and user-initiated searches, the Sentinel Platform delivers real-time actionable insights and operational oversight. 
 
Engineered for durability, longevity, and proactive intelligence, the Sentinel Blade provides a robust BLE tracking solution suitable for both personal and professional deployments.
