NFC vs UWB
NFC works at touch range for simple tap interactions, while UWB provides centimeter-level spatial accuracy at up to 200 meters. UWB enables direction-and-distance awareness for precise positioning. Modern smartphones combine both: NFC for authentication, UWB for spatial context like digital car keys.

Use NFC for tap-to-authenticate; UWB when precise spatial positioning is needed, such as walk-up-and-unlock car keys.
