ITPEC IP October 2022 — Question 12 of 100

NFC provides radio communication over a very short distance, commonly about 10 cm, for devices such as IC cards and tags. Its short range supports tap-based payments, access cards, identification, and small data exchanges between nearby devices.

Answer (a)

Why not others:
- tens-of-meters wireless LAN communication describes Wi-Fi

- infrared communication is a different optical wireless technology

- satellite-based positioning describes GNSS or GPS

Key rule: Near Field Communication is intentionally short range and is activated by bringing compatible devices or tags very close together.
