# 為什麼要使用「信用卡3D驗證」？

信用卡安全驗證就是更具安全保障的Visa驗證、MasterCard SecureCode、JCB之「3D驗證」服務。 是由Visa、MasterCard、JCB國際組織所提供之網路安全認證服務，讓您使用信用卡線上消費之前，再輸入一組您自行設定的專屬密碼；或是由信用卡公司提供僅能使用一次的動態密碼，確保只有您本人才可以使用自己的信用卡成功交易，安心享用線上消費服務。\
（**麻吉付在綁定信用卡時會產生一筆新台幣 1 元的過卡交易以確認您的信用卡，不會實際請款**）

各家信用卡公司驗證畫面不同，下面以中國信託為例。

***小提醒：如果您在輸入信用卡簡訊 OTP 驗證碼後出現逾時通知，請檢查手機中的時間設定需為「自動判斷日期和時間」，設定完畢後重開機再試一次。***
