Many character strings are printed on the password card in matrix form. When users use electronic banking to make payment transactions such as external transfer, B2C shopping and payment, the electronic banking system will randomly give a set of password card coordinates.
The customer finds the password combination from the card according to the coordinates and inputs it into the electronic banking system. Only customers who correctly enter the password combination can complete the relevant transactions. The password combination is valid once, but invalid after the transaction is completed.

Precautions for online banking are as follows:
1, avoid using search engines.
Get the website address of online banking from regular bank outlets and remember that when logging in to online banking, try to avoid using third-party channels such as search engines. Because some fake online banking websites are likely to be hidden in the search results, once clicked, they are likely to fall into the trap unconsciously.
The best way is to register the correct online banking website in the browser's favorites, and all future visits will be entered by clicking the link in the favorites to ensure that you will not visit the wrong website.
2. Set mixed password and double password.
The password setting of online banking should avoid being related to personal data. It is recommended to use a mixed password of numbers and letters to improve the difficulty of password cracking and keep it properly. Trading passwords should be avoided as much as possible.
3. Check the transaction records regularly.
Regularly check the business records such as transfer and payment handled by online banking, or customize the account change notice through SMS to keep abreast of account changes.
4. Keep the digital certificate properly.
Avoid using online banking on public computers to prevent confidential information such as digital certificates from falling into the hands of others.
5. Be wary of email links
Online banks generally don't send out "system maintenance and upgrade" tips by email. In case of major events, the system will suspend service and the bank will announce the customer in advance. So, when you receive a similar email, be careful of fraud. Once the information is found stolen, you should immediately modify the relevant transaction password or report the loss of the bank card.
