Introduction
- RFID (Radio Frequency Identification) technology is revolutionizing how we track and manage assets across industries like logistics, healthcare, and retail. The two main types—passive and active RFID—serve different purposes based on range, power source, and cost. Today, with rapid innovation, the boundaries between these types are fading, offering new capabilities and smarter integration.
Latest Developments in RFID
- Extended Read Range for Passive RFID:
- Thanks to improvements in antenna design and chip sensitivity, passive RFID tags can now reach over 20 meters in optimal conditions.
- Battery-Assisted Passive (BAP) Tags:
- These hybrid tags include a small battery to activate only when needed, combining passive tag affordability with active tag performance.
- IoT and Edge Integration:
- Active and passive systems are being integrated into IoT platforms. Active tags now send real-time data (temperature, movement) while passive tags benefit from smarter readers.
- Sustainability and Cost Improvements:
- Passive RFID tags are now cheaper and more eco-friendly, with innovations like printable electronics and biodegradable materials.
- Enhanced Security Features:
- New encryption protocols and authentication tools are being implemented, especially in active RFID used for secure access and asset tracking.
Conclusion
- As RFID technology evolves, passive and active systems are converging in capability. Passive tags are reaching farther, active tags are getting smarter and more efficient. The choice today depends not just on budget, but on strategy and application.
