Ye Yunzhang said that to guard against the risk of bank cards, there is a sentence called "three big tricks" and "eight points of attention".

"Three tricks" refers to three major categories of deception.

The first is high-tech crime.

For example, installing a micro camera on the ATM machine, using high tech offenses such as stealing cards, etc., the two is to make use of people's psychological act of paralysis and credulity.

Such as false card empty card to drop, paste "notice" and so on.

The criminals posted a so-called "urgent notice" on the ATM machine, claiming that the computer virus surveillance center of the head office was urgent to notify that the ATM system was attacked by viruses. In order to ensure the safety of users' funds, users must pfer funds to designated accounts to upgrade the antivirus sequence.

However, as long as the user pfers funds into the account, he will be taken away by the criminals immediately. The three is to use others' ID cards and other valid documents as security, and apply for accounts to defraud the people. In order to solve these deceitful tricks, cardholders should be more careful in eight aspects.

First, when you get a card, you should check the password envelope. If the envelope is opened, it will be changed immediately; second, immediately change the password, do not use passwords such as telephone numbers, birthdays and other easy to decipher codes. Third, password and card number should not be easy to show people. As long as they know the password and card number, they can use high technology to raise cash.

Fourth, ID card and credit card are stored separately to prevent loss at the same time, because ID card without password can also be withdrawals, identity cards can not be easily borrowed; fifth, cards can not be put together with magnetic objects, to prevent degaussing; sixth, when operating, pay attention to whether there are cameras on the ATM machine and other redundant devices. "Eating cards" and cards must be promptly lost and changed after the loss of the card. Seventh, do not trust the "urgent notice" and "notice" to prevent fraud; when the consumption is in public places, the cashier should check carefully in order to avoid dropping. The return on the ATM machine is not allowed to be lost, because there is a card number on the card.
