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 parts: the RFID tag and the RFID reader.
-
RFID Tag: This component includes an antenna, a circuit, and a microchip. The antenna receives and transmits radio signals, while the microchip stores data related to the item being tagged.
-
RFID Reader: The reader emits a radio signal that activates the RFID tag, allowing it to transmit its stored data. The reader then captures this data for processing.
Step 2
6.1.2 Differentiate between a passive and active RFID tag.
Answer
There are two main types of RFID tags:
-
Passive RFID Tags: These tags do not have an internal power source. They only activate when they are within the magnetic field generated by the RFID reader. Passive tags are suitable for short-range applications.
-
Active RFID Tags: Unlike passive tags, active RFID tags are equipped with on-board batteries that provide power. This allows them to communicate over longer distances and continually transmit data even without the presence of a reader.
Step 3
6.1.3 Motivate whether it is advisable to use RFID tags for your stall management.
Answer
Using RFID tags for stall management can be highly beneficial. They allow for efficient tracking of inventory, reducing the occasions of stock discrepancies. However, it may not be advisable if:
- The stall lacks a designated entry or exit point to check for tags, leading to potential issues in tracking.
- There could be significant additional costs associated with implementing and maintaining RFID systems that might outweigh the benefits.
