RFID Metal Tags

RFID tags that can be used on the metals are popularly known as RFID metal tags. These are primarily used for encoding purposes. The encoding may be read-only, write once or full read-write depending upon the requirements of the user. These tags come in various shapes and sizes as needed by the application.

• Active tags: Active tags contain a battery that powers the microchip and allows it to transmit a signal to the reader
• Semi-active rfid tags: Semi active tags draw power from the magnetic field created for the reader-to-reader communication
• Passive RFID tags: Passive tags rely heavily on the magnetic field of radio waves to generate current which can be received by their antenna

How RFID metal tags work?

As it was discovered that radio waves are reflected by metals, there was a sudden demand for RFID metal tags that can be used on metals. Each of these RFID metal tags is equipped with a transponder with a small digital memory chip assigned to each product. Then an RFID antenna equipped with a transceiver and decoder emits a signal to activate the RFID tag so that it may store or retrieve the data. When an RFID metal tag passes through the magnetic field, it detects the activation signal and responds to it in a predefined manner.


A number of RFID demo kits are also available at RFID certification global hub, employing RFID metal tags as their key elements. We invite you to contact us to learn more about how RFID4U can be an effective part of your RFID implementation initiative.
