Merchant Acquiring and Card Authorization

Merchant acquiring connects a business that accepts cards with processors, payment networks, and card issuers. The Acquiring Bank supports the merchant-side acceptance and settlement relationship, while a Merchant Account defines how transactions are processed, funded, adjusted, and disputed. The Merchant Discount Rate summarizes specified card-acceptance charges relative to transaction value, but the contract and statement determine which costs are included.

Card Authorization is the issuer’s approval or decline decision before capture. An Authorization Hold temporarily restricts available funds or credit, but neither event proves final merchant funding. A Floor Limit is a separate terminal or acceptance threshold used in certain online-versus-offline authorization decisions.

For analysis or reconciliation, trace the same transaction across the authorization request, issuer response, hold, capture, clearing record, settlement batch, merchant statement, reserve movement, and bank deposit. The key controls are role clarity, transaction identifiers, gross-to-net reconciliation, funding timing, fraud monitoring, and evidence for refunds or chargebacks.
