Do I still need to open a credit card after I finish my credit card?
No need to open the card (activate). If it is not activated, the validity period of bank credit cards is generally 3 years, and individual banks will automatically expire.
However, once the card is opened (activated), an annual fee is required, which is free in the first year and free in the second year. If the card is swiped more than six times in the first year.
