ITPEC FE Subject A October 2025 Question 54
ITPEC FE Subject A October 2025 — Question 54 of 60
An IC tag (RFID — Radio Frequency Identification) stores data inside a built-in chip and transmits it wirelessly via radio waves without physical contact. The package is sealed and resistant to dirt/stains, and a reader can scan it from outside the package without touching it.
Why not others:
- (a) — RFID stores data internally in the chip; no external storage device is used
- (c) — RFID is contactless; inserting into a reader is characteristic of contact smart cards, not RFID
- (d) — GPS is a separate satellite-based positioning technology; RFID does not use GPS
Key rule: RFID = contactless radio-based reading, with data stored inside the chip itself.
