是先辨識臉孔後，再把手機靠近感應器哦
剛好跟你說的步驟相反
所以可以先辨識完臉孔，再考慮要不要靠近感應器進行購買

蘋果後續向Yahoo新聞財經記者David Pogue解釋，主因在於Craig Federighi示範時，紅外線相機系統同時偵測其背後位於座位區的觀眾臉譜，或是舞台上其他工作人員臉譜，因此造成系統判斷異常，因此要求手動輸入數字密碼作為驗證。
我用兩個人的名字跟FaceID當關鍵字搜尋，找到更新後的新聞，你該更正一下你之前接收的錯誤資訊。
In fact, though, Face ID performed perfectly. It appears somebody at Apple set up the phone incorrectly.
事實上，Face ID運作得很完美，似乎是某個蘋果工作人員設定錯誤造成問題。
To see what really happened, just look at the screen Federighi was confronting. It says, “Your passcode is required to enable Face ID.”
要看看發生什麼事，可以看投影螢幕上Federighi遇到的狀況，上面寫著：「需要你的密碼來啟動Face ID。」
[中間省略]
Exactly the same system is at work on the iPhone X. You can unlock a sleeping phone with face recognition. But if the phone has been restarted or shut off, you still have to enter your password manually.
iPhone X上有著同樣的系統(設計)。你可以用臉部辨識來解鎖手機，但是如果手機剛被重開機，你仍需要手動輸入密碼。
Pogue的結論是：「問題出在工作人員白目，而不是Face ID有問題，Face ID運作起來完美無瑕。」

原文後續更新：
[UPDATE: Commenters have noted that the “passcode is required” message doesn’t have the same wording as the one that you see, on a Touch ID phone, after a restart. Instead, it resembles the message you see when someone has tried Touch ID unsuccessfully too many times. If Face ID uses the same scheme, we can’t know who had tried it unsuccessfully—stage crew? keynote team member?—but it’s safe to assume that it wasn’t Federighi. If he had tried and failed before the show, he certainly would have insisted on troubleshooting the phone after the first failure. In other words, something went wrong, but it wasn’t Face ID misbehaving.
大意：發表會上出現的「請輸入密碼」畫面比較像是Touch ID被亂用太多次時跑出來的畫面，所以實際上Face ID並沒有出錯。要怪就得怪發表會的工作人員。
（個人猜測大概是某隻壁雕手賤去亂玩準備要放上台的機子，搞到手機自己鎖起來。）
