🏷️ 名 (name) + 札 (tag/label) = a name tag
名 means name and 札 means tag or card, so 名札 is literally a name tag. Its reading なふだ is 名 (na) + 札 (fuda), so the sound also carries the meaning.
名 — evening 夕 + mouth 口
A compound ideograph: in the dark of evening (夕), one cannot recognize others by sight, so the mouth (口) calls out a name to identify oneself. The original sense of 'name' broadened to include reputation, fame, and a measure word for people.
