QR Codes, RFID & LIDAR
QR codes, RFID, and LiDAR are the identification and sensing technologies that give supply chains real-time visibility into where items are, in what quantity, and in what condition. QR provides cheap, ubiquitous optical tagging; RFID adds passive or active wireless reads at scale; LiDAR supports geometry capture, dimensioning, and autonomous-vehicle navigation in yards and warehouses. Together they enable the data layer that powers WMS, traceability, robotic fulfillment, and dock-to-stock automation.
