Application of Passive RFID Technology

Passive Internet of Things (IoT) is an emerging IoT technology that enables communication and data exchange between items through various sensors and devices. Sensor nodes do not require built-in batteries or other energy supply devices, but instead use external signals for operation. Radio Frequency Identification (RFID) technology is a simple and low-cost solution for the passive Internet of Things, suitable for scenarios that require simple tracking and monitoring of items. The sensor devices in this technology can be used for a long time interregional operation reduces maintenance costs and improves work efficiency. Therefore, it is a promising technology that can bring tremendous changes to various industries. In recent years, this technology has been widely applied in many fields, including logistics and supply chain management, industrial automation, intelligent agriculture, and health monitoring. This article elaborates on the practical application of the latest passive RFID technology, providing reference for more application scenarios in the future.
