Ask for credit card repayment details (I gave my mother 2500, and I don't want her to know. )

Tell her in advance that it's no big deal to buy another one if you lose it.

If the cardholder doesn't know about the credit card consumption, the overdue repayment is likely to affect the personal credit rating. Once it enters the credit blacklist of the People's Bank of China, it will be more serious than the loss reporting of credit cards.

If you have the ability to make up the money, you can make up it before the repayment date and deposit it in any branch of China Merchants Bank. However, at present, many banks will provide customers with SMS notification function when providing credit card or loan services, so when you swipe your card to spend money and pay back money from your account, the credit card holder is likely to receive such a SMS, so it's nothing to tell her, which can better prove the authenticity of your lost mobile phone and your purchase of mobile phone by swiping your card.
