  • The Authorization Process – The cardholder requests a purchase from the merchant. The merchant submits the request to the acquirer. The acquirer sends a request to the issuer to authorize the transaction. An authorization code is sent to the acquirer if there is valid credit available. The acquirer authorizes the transaction. The cardholder receives the product.
  • The Batching Process – The merchant stores all the day’s authorized sales in a batch. The merchant sends the batch to the acquirer at the end of the day to receive payment
  • The Clearing Process – The batch is sent through the card network to request payment from the issuer. The card network distributes each transaction to the appropriate issuer. The issuer subtracts its interchange fees, which are shared with the card network, and transfers the amount. The card network routes the amount to the acquirer.
  • The Funding Process – The acquirer subtracts its discount rate and pays the merchant the remainder. The cardholder is billed.
