On Metal RFID Tags are RFID tags designed to work optimally on metal surfaces. They are modified to overcome the challenges that an ordinary RFID tag would experience when operating on metal surfaces. For example, they have been enhanced to avoid detuning and reflecting of RFID signals.
These modifications ensure that you get a better read range and overall improved functionality. Manufacturers use the following techniques to enhance the functionality of RFID tags on metal surfaces:
- Provide a small space between the antenna and the metal. The spacer serves to protect the antenna from the adverse effects of the metal. This approach results in relatively big tags.
- Focus on making a specialized antenna with a unique ability to use signal reflection and metal interference for a better read range.
The on-metal tags are essential in asset tracking, industrial manufacturing, pipeline maintenance, and weapon tracking.
