TOPIC 1.4 - RFID

RFID uses "A" to transfer data between reader.

What is "A"?

• Electromagnetic Wave

• Radio Frequency Wave

• Microwave

• Light

RFID allows moveable item for identification, categorize, tracking and business transaction.

• True

• False

In an RFID system, "B" represents the transponder part and "C" represents the host section. What do "B" and "C" stand for?

• "B" = RFID reader;

  "C" = Computer.

• "B" = RFID tag;

  "C" = Computer.

• "B" = Antenna;

  "C" = Computer.

• "B" = RFID tag;

  "C" = Antenna.

It radiates the RF signal to and receives the signal from the transponder in an RFID system.

"D" is a type of RFID tag. "D" does not contain a battery. "D" include 2 parts, an integrated circuit and an antenna. What is "D"?

Semi Active Tag contain an antenna and a "E". Due to "E", the live span for Semi Active Tag is limited. What is "E"?

Active Tag will transmit information stored in the tag when it received RF signal from the antenna.

• True

• False

Passive Tag consist a battery.

• True

• False

Which of the following statements are correct?

• Passive tag is expensive when compared to active tag.

• Active tag is bigger that semi active and passive tag.

• Semi active tag have long life span.

• Active tag and semi active tag consist a battery.

The diagram depicts the fundamental operation of RFID. "1" shows the mechanism by which the antenna communicates with the transponder. Define the procedure "1" in a single word.
