Is it illegal to swipe more bank cards for no reason?

Bank cards are inexplicably expensive, and generally do not get into lawsuits. Because of the bank's fault, the bank card has more money, which belongs to unjust enrichment and the bank has the right to recover it. You should return it. If you refuse to return it, it may constitute criminal responsibility.

First of all, this extra money is caused by the bank's operational mistakes, which belongs to unjust enrichment in law. If the bank asks for repayment, it must be repaid; If you refuse to return it, it will constitute a crime of embezzlement, and you will be investigated for criminal legal responsibility and sentenced to fixed-term imprisonment.

The phenomenon of too much bank card money mainly includes:

1, the bank staff is negligent, and the bank staff accidentally entered the wrong amount when handling the counter business, which will lead to more money in the bank card, but the staff will definitely find this problem when checking out at night and will get the money back. You just need to cooperate. This situation is not illegal.

2. Transmission error. Many people accidentally enter the wrong account number when handling the transfer business on ATM machines, and they will put money into your account, but when the transferor finds out, he will also get the money back, so it is not illegal for you to return the extra money.
