Cannot be activated, not your own.

A credit card is a personal financial instrument that can only be activated and used by the cardholder. Credit card companies require verification of the cardholder's identity to ensure security and prevent fraud. If someone else knows the credit card information but is not the cardholder, the credit card cannot be activated. This is to protect the interests of cardholders and reduce risks. Therefore, even if someone else knows the credit card information, they cannot activate it because it does not belong to them.
