Radio-frequency identification (RFID) Technology
RFID technology is a wireless communication technology that uses radio waves to automatically identify and track various tagged objects. It involves the use of tags, readers, and software to enable the identification and tracking of objects.
Components of an RFID system
An RFID system consists of three main components:
1. Transponder: This is the tag or label that is attached to the object being tracked. The tag contains a microchip that stores information about the object and an antenna that receives radio waves from the reader.
2. Reader: This is the device that communicates with the tag and collects the information stored on it. The reader emits radio waves that are received by the tag and sends the information back to the reader.
3. Transmitter: This is the device that sends the information collected by the reader to a central database or computer system for processing and analysis.
Correct statements
1. It is a technology that uses radio waves to automatically identify various tagged objects.
This statement is correct. RFID technology uses radio waves to identify and track tagged objects.
2. Transponder, receiver, and transmitter are the three components of an RFID system.
This statement is also correct. The three main components of an RFID system are the transponder, reader, and transmitter.
Therefore, both statements are correct, and the correct answer is option C.

With reference to the Radio-frequency identification (RFID) technology...
Baggage tags equipped with radio-frequency identification (RFID) will soon be available at Delhi’s Indira Gandhi International Airport, marking a first of its kind for the country.
- Radio-frequency identification (RFID) is a technology that uses radio waves to automatically identify various tagged objects. Radio Frequency Identification (RFID) is a wireless tracking method that uses tags and readers to track objects.
- Transponder, receiver, and transmitter are the three components of an RFID system.
- The RFID reader continually sends radio waves of a specific frequency in RFID system. If the object to which the RFID tag is attached is within the range of the radio waves, it provides feedback to the RFID reader, which then identifies the object based on the feedback.
Radio-frequency identification (RFID) technology Vs barcodes
- RFID uses radio waves to communicate data from RFID chips to readers that do not require line of sight in order to obtain the data, whereas barcodes use light to read the black-and-white pattern printed on the sticky tag. An RFID tag can communicate with a powered reader even when the tag is not powered.
- When printed on paper or sticky labels, barcodes are more susceptible to wear and breakage, which can affect their readability. RFID tags, on the other hand, are sometimes placed in plastic labels or into the object itself, making them more durable than barcodes.
- In contrast to barcode scanners, RFID scanners can process dozens of tags in a single second. Also, barcodes are simple and easy to copy or counterfeit, whereas RFID is more complicated and difficult to replicate or counterfeit.
- Unlike barcodes, which must in line of sight, RFID tags need not be.
- Also, RFID tags are expensive compared to barcodes.
Hence both statements are correct.
