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:
-
RFID Tag: This is the component that contains the antenna, circuit, and microchip. It is responsible for receiving and storing the information, which can be transmitted to an RFID reader when in close proximity.
-
RFID Reader: This device emits radio signals to communicate with the RFID tags. It reads the information stored in the tags and sends it to a database for processing and inventory management.
Step 2
6.1.2 Differentiate between a passive and active RFID tag.
Answer
The main differences between passive and active RFID tags are:
-
Passive RFID Tag:
- Does not have a power source.
- Only activates when within the magnetic field of a reader.
- Generally has a shorter range and lower cost.
-
Active RFID Tag:
- Contains an internal battery that powers the tag.
- Can transmit signals over longer distances, making it suitable for tracking high-value items over vast areas.
- More expensive due to its advanced features.
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 is advisable because:
- Efficiency: RFID tags streamline the process of tracking inventory, reducing the time spent on manual checks.
- Accuracy: They minimize errors in stock management, leading to more reliable inventory data.
- Customer Experience: Enhanced stock management can improve product availability, thus enhancing customer satisfaction.
