How do active RFID tags function compared to passive tags?

Active RFID tags function by transmitting data continuously without prompting. This is made possible because active tags are equipped with their own power source, typically a battery, which allows them to emit signals at regular intervals or in response to specific conditions, such as the detection of another signal.

This continuous transmission capability enables active RFID tags to provide real-time tracking and highly accurate location information, making them ideal for applications where consistent monitoring is essential, such as in supply chain management or asset tracking.

In contrast, passive RFID tags rely on energy from an external reader to operate, which means they only transmit data when prompted by the reader's signal. This fundamental difference in how power is managed and data is transmitted distinguishes active tags from passive tags significantly.
