EMV® 3-D Secure ARes(Authentication Response Message)

EMV® 3-D Secure ARes(Authentication Response Message)簡介。

EMV® 3-D Secure ARes(Authentication Response Message)（3DS驗證回應訊息）是發卡銀行(Issuer bank)的ACS(Acess Controller Server)對AReq(Authentication Request Message)（驗證請求訊息）的回應結果。

ARes可指出持卡人(Cardholder)是否已被驗證，或是持卡人是否需要進行更多動作來完成驗證。每筆交易只會有一筆ARes訊息。
