First, set a complicated password. Set passwords that are easy to remember but difficult to decipher, and avoid using easy-to-guess or simple and orderly numbers such as birthday, ID number and telephone number as passwords. When keeping cards and passwords, keep bank cards separately from ID cards, passports or other valid certificates to prevent them from being lost at the same time. Don't write your password or store it where others may see or get it, don't store it in your mobile phone or write it on the back of your bank card. Bank cards cannot be lent to others.

Second, pay attention to credit card transactions. Pay attention to whether the card slot has been modified when trading on ATM. Don't let the card leave your sight when the special merchant swipes the card, and confirm whether the cashier swipes the card repeatedly, and contact the bank if necessary. After the transaction is completed, it is necessary to check whether the card returned by the merchant is really my card.

Third, turn on SMS notification. It is understood that most banks have SMS notification service. When using a credit card, cardholders should try to open a credit card SMS notification service. Once a credit card transaction or fund change occurs, the cardholder can know it by SMS at the first time. If the cardholder finds that there is an abnormal transaction in the credit card through SMS, he can report it to the police or the bank quickly, thus enhancing the security of the use of the bank card to a certain extent.

Fourth, replace the chip card in time. The chip card takes the chip as the transaction medium and adopts advanced chip encryption technology to support non-contact off-line transactions. Replacing the magnetic stripe card usually used with a safer chip card in time can effectively reduce financial fraud incidents such as bank card copying.

Fifth, protect the security of personal information. When handling bank cards, you should handle them through door-to-door personnel, marketing outlets and bank employees. Be sure to verify the identity of the other party, such as checking work documents to prevent criminals from stealing personal data.

At the same time, indicate the words "only for bank cards" and the date on the application documents such as the copy of ID card and income certificate to ensure the specificity of the materials. Many cardholders handle business at ATMs and counters of banks, and throw away the receipt after tearing it up or throw it away at will without tearing it up, which may reveal the information of depositors. It is suggested that the cardholder must completely crush the receipt or collect it by himself after handling the business.
