In batch credit card processing, a merchant submits multiple authorized credit card transactions to its payment processor at one time—frequently the entire day's worth at the close of business for that day. The alternative to batch processing is real-time processing.
Credit card processing fees encompass three types of fees (interchange, assessment and payment processing) that get distributed to three separate financial institutions (issuing bank for the card, credit card network and payment processor) involved in facilitating the card payment process.
