Active RFID
Active RFID stands for Active Radio Frequency Identification. Unlike passive RFID tags that rely on the reader's signal to activate, active RFID tags possess their own internal power source, typically a long-lasting battery. This self-powered nature empowers them to continuously transmit their unique identification code and any additional data they carry, enabling real-time location tracking and data retrieval.
Key Features of Active RFID:
- Self-Powered: Active RFID tags are equipped with their own power source (such as a battery), eliminating the need for a reader's signal to activate them. This autonomy extends their range and data transmission capabilities.
- Customizable Communication: To conserve battery life, these tags are programmed to transmit at set intervals, which can be adjusted according to specific requirements.
- Enhanced read Range and Accuracy: Active RFID systems offer a more extensive read range and higher accuracy in tracking compared to passive RFID systems.
Active RFID Applications
Active RFID finds widespread applications across diverse industries, including:
- Tool and equipment Management
- Environmental Monitoring
- Animal Tracking
Bluetooth Low Energy (BLE) – a fresh twist in Active RFID
Bluetooth Low Energy (BLE). BLE, is like an energy-efficient version of Bluetooth, it is a short-range wireless network protocol designed for quick and automatic wireless connections. This technology is increasingly being adopted in sensors, wearables, and IoT devices for its ability to exchange small amounts of data while consuming minimal energy.
At Cisper, we proudly offer a range of BLE tags from Confidex. The Confidex Viking Classic is a good example of an industrial beacon to track the location of assets and people, and to sense the environment.
With the Williot Starter Kit and the Williot Enablement Kit you can experience the revolutionary Williot BLE pixels that use energy harvesting technology to activate them.
Active RFID vs. Passive RFID: Unveiling the Differences
While both active and passive RFID technologies utilize radio waves for data transmission, they differ significantly in their power source, read range, and data capabilities.
