Which one of the following statements is true about radio frequency identification (RFID)?

Explanation

Radio frequency identification (RFID) are items which use radio technology to identify itself and its location subject to having appropriate hardware and software.

RFID tags are made of three different components: an RFID chip, which is an integrated circuit (IC), an antenna, and a substrate.

A RFID Reader is a device that uses radio-frequency waves to wirelessly transfer data between itself and a RFID tag/label in order to identify, categorize and track assets. When combined with the right RFID software, a RFID reader can identify objects quicker, more accurately, at a reduced overall cost, and at various points of the object’s lifecycle.

Passive RFID systems use tags with no internal power source and instead are powered by the electromagnetic energy transmitted from an RFID reader. Passive RFID tags are used for applica-tions such as access control, file tracking, race timing, supply chain management, smart labels, and more.

Active RFID systems have three essential parts – a reader or interrogator, antenna, and a tag. Ac-tive RFID tags possess their own power source – an internal battery that enables them to have ex-tremely long read ranges as well as large memory banks.
