Consider the following statements with reference to Radio Frequency Id...
- Radio Frequency Identification (RFID) is a type of passive wireless technology that allows for tracking or matching of an item or individual. Hence, statement 1 is not correct.
- The system has two basic parts: Tags and Readers.
- The reader gives off radio waves and gets signals back from the RFID tag, while the tag uses radio waves to communicate its identity and other information. Hence, statement 2 is not correct.
- A tag can be read from up to several feet away and does not need to be within the direct line-of-sight of the reader to be tracked.
- The technology has been approved since before the 1970s but has become much more prevalent in recent years due to its usages in things like global supply chain management and pet microchipping.

Consider the following statements with reference to Radio Frequency Id...
Statement 1: RFID is a type of active wireless technology that allows for tracking or matching of an item or individual.
Statement 2: The reader gives off infrared waves and gets signals back from the RFID tag.
Explanation:
Radio Frequency Identification (RFID) is a technology that uses radio waves to automatically identify and track objects or individuals. It consists of two main components: an RFID tag and an RFID reader.
RFID Tag: An RFID tag is a small electronic device that contains a unique identifier and an antenna. The tag can be attached to or embedded in an item or individual. There are two types of RFID tags: active and passive.
- Active RFID Tag: An active RFID tag has its own power source, such as a battery, and can actively transmit signals to an RFID reader. These tags can have a longer read range and are often used for tracking high-value assets or individuals. Therefore, statement 1 is incorrect.
- Passive RFID Tag: A passive RFID tag does not have its own power source and relies on the energy transmitted by the RFID reader to power it. When the reader emits radio waves, the tag's antenna captures the energy and uses it to transmit its unique identifier back to the reader. Passive RFID tags have a shorter read range and are commonly used for inventory management and access control.
RFID Reader: An RFID reader is a device that emits radio waves and captures the signals transmitted by RFID tags. The reader can be handheld or fixed in a specific location. It communicates with the tags and receives their unique identifiers or other data. RFID readers can operate at different frequencies, such as low frequency (LF), high frequency (HF), and ultra-high frequency (UHF).
Statement 2 suggests that the RFID reader gives off infrared waves and gets signals back from the RFID tag. This statement is incorrect as RFID technology uses radio waves, not infrared waves, for communication between the reader and the tag.
Therefore, neither statement 1 nor statement 2 is correct.
Statement 2: The reader gives off infrared waves and gets signals back from the RFID tag.
