Core Capabilities

Device-Driven Automation

Physical device events (LPR, UHF, weighbridge) initiate and progress trips without manual intervention

Authorization-First Access

Contract-based vehicle permissions enforce site, zone, and time-window access at every gate

Weight Correlation Engine

Scale readings automatically correlate to active trips via device detection at each weighbridge

Event-Sourced Lifecycle

Immutable event trail enables state reconstruction, audit compliance, and forensic analysis
