1 The credit card is not activated and will not be affected if it is left unused. After the validity period of the card has expired, the bank will not issue a second card. If you want to use the card at this time, you have to call the bank to resend the card. The customer pays Money (to pay card fees, postage, etc.). There are also banks that will use various methods to trick you into activating it. You should pay attention to keeping your credit card inactive to avoid problems.
2 If the credit card is not used after activation, it will incur annual fees. If you owe the annual fees, you will have a bad credit record. Affect your credit record and thus your loan.
3 After a long time, it will be stolen by children (although children are not that smart), or by criminals who know your information! But you somehow forgot this card.
. . . . . This is all for writing first,
Please be satisfied and thank you!
