Credit card pre-authorization is a temporary balance hold in your credit card to guarantee a smooth transaction between our users and money changers. The actual balance will not be reduced if you complete the transaction before the designated time. 

信用卡預授權是指一筆暫時在信用卡中預留的信用額。只要在指定時間前完成交易,預授信用額並不會被收取。
