Hello, I sent you a card with my credit card, which belongs to debit card. You need to activate it to use it. You can activate it automatically through the counter or 95555- 1. The initial password is the last six digits of the ID number. If the last digit of the ID card is X, the initial password is the last six digits before X. For example, if the last digit of the ID card is "123456X", then the initial password is 123456. If the last digit of the ID card is X in the process of inputting the ID number, it has been replaced by "*". If the card needs to be closed, it needs to be activated before it can be closed at the outlet.
