Hello, if you apply for all CMB credit cards, the main purpose is to prevent the cards from being damaged. Once one card is damaged, you don't need to change it. There is a 15 yuan/card fee for changing the damaged card, so you can use another card directly.

if you want to use the cash advance function, within the available cash advance limit, the daily cash advance amount of each card does not exceed RMB 2,, so if you have two cards, you can advance more funds.
