The cash is in the bank card given by my mother. Will she receive a reminder from the bank?

Yes Because the phone number bound to the bank card is the mother's, as long as the bank card is like this, every time there is a deposit or consumption, the mother's mobile phone will receive the information sent by the bank so as to know the whereabouts of each sum of money. Bank card refers to a credit payment tool issued by commercial banks (including postal financial institutions) to the society with all or part of the functions of consumer credit, transfer settlement, cash deposit and withdrawal, etc.
