Who handles an online card payment

  • Acquirer: the financial institution that supports card acceptance for the merchant.
  • Issuer: the financial institution that issued the shopper’s card.
  • Gateway: the service that connects the checkout to payment processing systems.
  • Merchant identification number (MID): an identifier used in a merchant processing relationship.

What the transaction and funding states mean

  • Authorization: the card payment request is approved, which can create a hold for an amount.
  • Capture: submission of a previously authorized payment for processing and settlement.
  • Settlement: the processing stage that accounts for captured card transactions. A payout is the resulting funding movement to the merchant.
  • Reserve: proceeds or other amounts held under the account terms against possible future obligations.

What appears in customer and support records

  • Descriptor: the text that identifies the charge on a customer’s card statement.
  • Refund: a credit against a prior payment. A void cancels an eligible transaction before it settles.
  • Dispute: a claim raised through the customer’s bank. A chargeback is the reversal associated with the dispute process.
