EMV® 3-D Secure 3DS Requestor

EMV® 3-D Secure 3DS Requestor 簡介。

簡單說3DS Requestor的角色就是商家接收信用卡付款資料的web server。

Consumer Device透過3DS Client(3DS Requestor App（也就是商家的App）的3DS SDK或瀏覽器的3DS Method)蒐集並傳遞資料給3DS Requestor。3DS Requestor再將Consumer Device蒐集好的驗證資料轉交給3DS Server發起3DS驗證。

3DS Requestor和3DS Server在3DS驗證流程中雖然是不同元件，但現實應用上有可能整合在一起。
