What does it mean for Jinhua bank card to be deducted 0000?

In the first case, the bank card has a fixed monthly deduction. The amount deducted from this money will not be too much, such as SMS notification fee, which is usually 3-5 yuan, and will be deducted automatically every month. In the second case, the depositor handles the withholding. Many people have bound bank cards in various apps of mobile phones, and opened services such as phone bill withholding and continuous monthly subscription for members. Later, if they forget, the bank card will automatically deduct money every month. In the third case, automatic repayment. If you open a lending platform such as Flower Shop and Borrowing Shop, or use services such as credit card consumption, and you have a loan, if you don't repay it on time before the repayment date, the bound bank card will also be automatically deducted. In the fourth case, I encountered a scam. Previously, an uncle received text messages continuously in the early morning, and the bank card was inexplicably deducted several times, totaling more than 5,000 yuan. For example, in the case of such a large amount of money and continuous deduction, most bank cards have been stolen.
