Credit cards are generally valid for three years;
At the end of three years, the bank credit card center will evaluate the credit situation;
If you use it well and repay it on time, the service life will be extended;
A new card will be issued if it is used beyond the time limit, and it needs to be activated when it arrives;
The new card completely inherits the original card;
If the credit is bad and the repayment is not made on time, the extension will not be extended.
If you have other specific questions, I suggest you call the customer service staff of the bank, hoping to help you.
