Secondly, banks have no responsibility. Pay attention to the details I say below. ) All accounts are closed with your ID card. As for your reason that your friend took your ID card to cancel the account and you didn't know it, it is legally untenable. The bank has no obligation to prove whether your ID card was given to your friend voluntarily or whether your friend lied to you. I can only blame myself for trusting my friends too much and giving them to others. (In fact, many people don't pay attention to this detail in their daily life and give it to others at will.
But there is one detail I hope you can pay attention to in this link: you watched the surveillance video taken by the bank. Did your friend cancel the account with your ID card at that time, or did you cancel the account with both your ID card and her own ID card? This involves a principle: if it is presented at the same time, it is in full compliance with the law for her to cancel the account as your agent. If she takes advantage of being a bank employee and only uses your ID card, then it is illegal for her to cancel her account: she uses someone else's ID card to make profits for herself. In this way, banks will be responsible. According to similar cases I know, it will bear at least 30% of your losses, and if the court decides in your favor, it may reach 50%.
As for the evidence for your supplementary question: What evidence will the public security department specifically ask you to provide after you report the case, such as your short message and telephone records. Only when the evidence is conclusive will a criminal case be filed, and then it will be wanted or help you find this person. If you don't have any evidence to prove that your friend cancelled his account without your knowledge, then you can only go to your friend yourself and wish you good luck, hehe.
Therefore, the most important thing in the current situation is the details when closing the account. If your friend uses your ID card and goes through the cancellation procedures, you can get some money back, otherwise ~ ~ ~ ~ alas.
