The banking system deducts money in batches. According to the inquiry of the Financial Association, the settlement of credit card batch transfer transaction means that banks use the system to deduct money in batches without being present, and directly deduct money from the card by password, such as withholding water, electricity and coal, binding accounts, automatic repayment of credit cards and other batch payments, that is to say, they have participated in more than one financial project before, but the payment time is the same, so when multiple project payments occur at the same time, the bank will inform them of batch payments by SMS.
