How are card payments typically processed at the end of the day?

Card payments are typically processed at the end of the day through a batch processing system, where transactions are collected and sent in batches to the acquirer. This method allows for a more efficient and organized way to handle a large volume of transactions processed throughout the day. By grouping these transactions into batches, it minimizes the number of individual messages that need to be sent over the network, thus reducing processing costs and time.

Batch processing also allows for the reconciliation of transactions more seamlessly, as all transactions can be reviewed and verified together. This is particularly important for merchants and acquirers who need to keep accurate records of the transactions processed over a given period.

While some types of payments might be settled immediately, card payments often employ this batch approach, which is a standard operational practice in the payments industry. Collectively, this process enhances efficiency and security in the handling of card payments.
