Card storage: Once a debit card is lost or stolen, there is a risk of being fraudulently used or forged. The card should be kept as cash, and it should not be placed at will, let alone lent to others. Identity documents and debit cards should be kept separately.
Password protection: Some debit cards require the cardholder to set multiple passwords such as transaction, withdrawal, inquiry and login. It should be noted that the transaction and withdrawal passwords cannot be the same as other passwords.
Password settings should be easy to remember but difficult to decipher, for example, don't set your birthday or several consecutive or identical numbers as passwords. Don't tell the password to anyone, including bank personnel, police, etc. When entering the password for credit card withdrawal, you should pay attention to covering it with your hands and body.
