Cellular Tracker: QR Code Scanner with GPS and LTE Capabilities

The Cellular Tracker signifies an advancement in embedded systems used within industrial settings for supply chain management. It integrates three fundamental technologies�QR Code Decoding, Global Positioning System (GPS), and Cellular Network capabilities�into a unified system. Traditional devices often face cost and reliance challenges, especially concerning GPS and cellular functionalities. In this system, a scanned QR code promptly links with current GPS coordinates and transmits data via an LTE module to a remote cloud. This transmitted data provides real-time supply chain status on a web platform, ensuring operational transparency. In scenarios with poor network connectivity, data is stored locally and sent once connectivity is restored. The device enters a low-power mode after a defined period of inactivity. This integration, termed the Cellular Tracker�a QR Code Scanner with GPS and LTE capabilities�represents a practical, cost-effective, and energy-efficient solution compared to previous approaches in this domain.
