Terms and definitions

Learn the key terms, card types and interchange categories relevant to your business.

Interchange fees

The interchange fee is set by the card schemes (Visa, Mastercard®, eftpos® and UnionPay) and is paid by the acquirer (the Merchant's financial institution, in this case NAB) to the card issuer (the financial institution whose name is on the card). The fee per transaction varies depending upon the type of card, type of transaction and the method used to accept each transaction.

Interchange fees are charged per transaction and may be:

  • a percentage of the transaction value

  • a fixed amount (such as cents)

  • or a combination of both

  • Domestic (Dom) – Card issued by an Australian financial institution

  • International – Card issued by an overseas financial institution

  • CR – Transactions involving a credit account

  • DR – Transactions involving a debit card which provides access to the cardholder's bank account

  • Prepaid – Transactions involving a prepaid card

  • Electronic (Elec) – Transactions processed electronically, such as those made through EFTPOS terminals or online payment systems

  • Recurring Payment – Transactions where a customer has provided ongoing authorisation for a merchant to automatically debit their card at regular intervals (e.g. subscriptions or instalments)

Merchant service fees

Mastercard®, Visa, eftpos® and UnionPay® merchant service fees are service fees charged by NAB for providing merchant services in respect of those payment schemes. They include technology, fraud and risk management, compliance and regulatory obligations, customer support and servicing. Depending on your pricing structure, they may also include your interchange fees and scheme fees.
