RFID (Radio Frequency Identification) tags are a pivotal component of RFID technology, which is used for tracking and identifying objects, animals, or people through radio waves. These tags are essentially made up of a microchip attached to an antenna; together, they're encapsulated in a variety of forms like stickers, cards, wristbands, or even embedded in items. The microchip stores data, which can be read by an RFID reader.
