In American football, the NFC is the National Football Conference: one of the two big groups of teams inside the NFL. The other group is the AFC (American Football Conference). NFC teams play each other through the season; later, the NFC champion meets the AFC champion in the Super Bowl. People treat “the NFC” as a name, the way they say “the league,” not as a normal adjective you can put in front of just anything. You will hear it in sports news, scores, and Super Bowl talk. It is US sports English. It does not mean “a meeting” in general, and it is not a word you use for everyday plans.

NFC（國家聯會），美國職業美式足球兩大組之一，另一組是 AFC。台灣日常說的 NFC 多半指手機感應付款，那是另一個意思。
