1, U shield generally refers to U shield, which is the guardian of online banking security and always guards the security of online banking funds. Generally, when the bank opens online banking, the bank will give a U shield, which looks like a U disk, adopts high-strength information encryption, digital authentication and digital signature technology, and cannot be copied, which can effectively prevent payment risks and ensure the safety of customers' online payment funds.

2. When users open online banking, the bank will not charge any fees, but the U shield will be charged, and the fees charged by different banks are different. You can consult the bank when you open online banking. It is worth noting that the U shield used by users will have a time limit and can be updated in the bank after expiration.

3. Users can handle many businesses after opening online banking, such as transfer, payment, investment and financial management. Among them, inter-bank transfer can enjoy certain discounts, but there will be quota restrictions. It is worth noting that the time for inter-bank transfer to the account is 1 to 3 working days.

4. It is worth noting that if you accidentally lose your U shield, to ensure the safety of your online banking account, please immediately apply to ICBC outlets for freezing your U shield. If you confirm that the U shield has been lost, you can apply for a replacement certificate. After the application takes effect, you can download the certificate information again according to the original method of using U shield, or you can ask the bank teller to help you complete the operation.
