IoT

IoT (Internet of Things) connects everyday objects like appliances, industrial equipment, and sensors to the internet for data collection and control. Applications range from smart homes to factory monitoring and agricultural sensors.

QR codes bridge the physical-digital gap in IoT by providing instant access to device information, firmware details, and maintenance history through a simple scan. They also simplify device setup by encoding Wi-Fi credentials. Compared to NFC tags, QR codes offer significantly lower deployment costs and error-correction durability, making them ideal for large-scale IoT environments.
