Don't answer your question. Just talk about ICBC's online banking. ICBC customers can only have one online banking. To put it bluntly, an ID number can only have one online banking. But other cards under your name can be managed under this online banking, no matter where the cards are in the country. After applying for online banking, other cards can be added to online banking to realize the function of managing all accounts in one online banking. Therefore, after ICBC opens online banking, if you need to add other accounts, you can register online banking with your bank card, ID card and the bank card you need to add, and handle the business of adding registration cards at any ICBC personal outlet in the country. Besides, a U shield is enough. Also, due to the existence of off-site cards, there are charges for transferring money between different cards in online banking.
