ITPEC FE Morning October 2020 Question 72
ITPEC FE Morning October 2020 — Question 72 of 80
RFID (IC Tag) Characteristics — identify the key feature of RFID technology.
RFID tags store small amounts of data on an embedded IC chip and communicate via radio waves. Key characteristics:
- •Contactless reading: data is read wirelessly, without inserting or swiping the tag
- •Read through packaging: the tag can be scanned from outside a package or container
- •Durability: tags are resistant to stains and physical wear since the chip is encased
Why not others:
- (a) RFID tags store very small amounts of data (typically just an ID); they do not use external storage devices
- (c) Inserting into a magnetic reader describes magnetic stripe cards, not RFID — RFID is contactless
- (d) RFID does not use GPS; location-based display describes augmented reality or navigation services
Key rule: RFID = contactless radio-wave reading, works through packaging, no line-of-sight needed.
