# Proximity Tags ## What Are Proximity Tags? **Proximity tags** are small electronic devices or labels that use wireless technology to detect and communicate their presence when near a reader or another tag. They are fundamental to location-based services, asset tracking, and interactive applications. In my personal experience working with IoT projects, integrating proximity tags transformed how we managed warehouse inventory, providing real-time visibility that was previously impossible. ### How Proximity Tags Function: A Technical Perspective From a technical viewpoint, I find the evolution of these tags fascinating. My skill in embedded systems allowed me to appreciate the miniaturization of their components. They typically contain a microchip, an antenna, and sometimes a sensor or battery, depending on whether they are passive or active. #### Key Technologies Behind Proximity Tags * **RFID (Radio-Frequency Identification):** Uses electromagnetic fields for automatic identification. * **BLE (Bluetooth Low Energy):** Enables low-power communication with smartphones and gateways. * **UWB (Ultra-Wideband):** Provides highly precise indoor location tracking. ## TIANJUN Proximity Tag Solutions At TIANJUN, we engineer robust proximity tag solutions designed for enterprise reliability and innovative applications.
