RFID tags consist of an integrated circuit (IC) and an antenna that enables communication with RFID readers. They come in different forms, including passive and active tags. Passive RFID tags do not have a built-in power source and rely on the energy emitted by the RFID reader to operate. This makes them cost-effective and suitable for applications where the tags do not need to transmit data over long distances. For more check - https://www.idsolutionsindia.com/product/rfid-tags/
