When making a transaction, the responsible bank of the bank card used will deduct a part of the handling fee in batches.

It is normal for bank cards to be charged by uc, and most banks will charge a certain handling fee when conducting transactions. UC withholding means that when a bank makes a settlement, it processes multiple transactions together to improve efficiency and convenience. UC withholding occurs when a merchant submits multiple authorized credit card transactions to a bank.

Banks will handle these transactions in a lump sum, especially at the end of business. This batch processing method can improve the efficiency of transaction processing and reduce the time and cost of a single transaction.
