Worked Solution & Example Answer:6.1 It has been suggested by a trusted friend that in order to keep the stock safe at the stall, RFID tags must be attached to the clothing - NSC Information Technology - Question 6 - 2017 - Paper 2
Step 1
6.1.1 List AND explain the TWO PARTS that make up the RFID system.
Answer
The RFID system consists of two main components:
-
RFID Tag: This contains the antenna, circuit, and microchip. The tag is responsible for storing the unique information and sending it to the reader when activated.
-
RFID Reader: This device emits radio signals to communicate with the RFID tag. It reads the signals sent by the tag and converts them into usable data.
Step 2
6.1.2 Differentiate between a passive and active RFID tag.
Answer
Passive RFID tags do not have their own power source; they receive power from the reader's magnetic field to transmit their information. In contrast, active RFID tags have an onboard battery that allows them to send signals over longer distances and independently of the reader.
Step 3
6.1.3 Motivate whether it is advisable to use RFID tags for your stall management.
Answer
Using RFID tags can be advisable for stall management as they enhance tracking efficiency and reduce manual errors. However, considering the physical layout of the stall is essential, as it may be impractical if there is no designated entry or exit point for scanning.
