What is the fundamental component of an RFID tag?

The fundamental component of an RFID tag is the combination of a chip and an antenna. The chip, or integrated circuit, is responsible for storing and processing the data associated with the tag, while the antenna transmits and receives radio frequency signals to and from a reader. Together, these components allow the RFID system to communicate with the tag, enabling identification and tracking of objects without the need for direct line-of-sight, as would be required in traditional barcoding systems.

The chip contains the necessary information about the tagged item, and the antenna is essential for enabling communication over distances, which can vary depending on the specific RFID technology used. This fundamental structure supports various applications, from inventory management to supply chain logistics, showcasing the versatility of RFID technology in modern data tracking and identification practices.
