• HCE Example: https://www.slideshare.net/ChienMingChou/hce-tutorialv-v1
• Important: 確定系上的NFC Reader會發出APDU的Command，不然無法運作。

Register AID

1. 需要跟廠商要求是哪種類別 (目前有payment, other)
2. 需要辨識那些AID

讀卡機傳來的APDU:格式 (可能需要跟廠商要他們的格式)

實際測試程式碼

Card Reader

Data格式:

• 

傳輸Select AID Command:

• 

接收到Card回應的消息，判斷正確就Request Card Number

• 

Host Card Emulation:

• 用以判斷Card Reader傳來甚麼請求，並回傳對應資料

1. 是否指定AID正確後，回傳一個正確訊息，就可以開門?
2. 是否AID正確後，還會發出請求要求卡號，來開啟門禁?
