ITPEC FE Morning April 2019 Question 22
ITPEC FE Morning April 2019 — Question 22 of 80
RFID (Radio-Frequency Identification) — identify the correct use case for RFID technology.
RFID uses small wireless chips (tags) to identify and track objects or people via radio waves.
Correct: (b) Identification and management of personnel or items using a very small wireless chip — this is the core RFID use case.
Why not others:
- (a) Infrared data transmission — describes IrDA, not RFID
- (c) Reading a digital code printed on paper — describes barcode/QR code scanning
- (d) Audio between cellphone and headphones — describes Bluetooth
Key rule: RFID = radio-frequency + wireless chip/tag for identification and tracking.
