ITPEC FE Morning October 2023 Question 74
ITPEC FE Morning October 2023 — Question 74 of 80
RFID (Radio Frequency Identification) uses radio waves to read data stored on a small embedded chip without physical contact. The tag can be read through packaging, dirt, or other materials, making it "stain-resistant" and readable from outside the package — no line-of-sight or physical insertion required.
Why not others:
- (a) RFID stores only small amounts of data (typically a unique ID or a few bytes); it has no external storage device.
- (c) RFID requires no physical insertion — contactless reading via radio waves is its defining feature.
- (d) RFID does not use GPS; it is a short-range radio technology, not a satellite-based positioning system.
Key rule: RFID = contactless read/write via radio waves; data is readable through packaging without physical contact.
