From 3DS to SSL, language around payments can be complicated. And while we pride ourselves on being payments nerds, we know that not everyone is as passionate about this terminology as we are. That’s why we’ve put together this list of some of the most common industry terms and their definitions. We hope it helps shed some light on the payments industry (and what the heck we’re all talking about). Keep in mind that the use of these terms may differ outside of Braintree or across different countries and regions.

ARN: Acquirer Reference Number. A unique number that tags a credit or debit card transaction when it goes from the merchant’s bank through to the cardholder's bank. Also called a trace ID, this number is often used to determine where a transaction's funds lie at a certain time.

Cardholder: The customer to whom a credit or debit card has been issued; the individual authorized to use the card.
Chargeback: The result of a cardholder disputing a specific credit or debit card transaction with his or her issuing bank. The issuing bank initiates a chargeback with the acquiring bank, which then filters the chargeback down to the merchant account level The amount of the disputed transaction is immediately withdrawn from the merchant's bank account, and the merchant has a set amount of time in which to defend the chargeback, depending on the rules of the card association. A chargeback fee is usually charged to the merchant in addition to the amount of the transaction.
Chargeback defense: The transaction information a merchant needs to defend against a chargeback, such as the amount, an invoice, a customer verification/signature, and/or shipping documents.
Credit card: A payment card that enables cardholders to purchase goods and services on credit. The cardholder is then billed by the issuing bank for repayment of the credit extended.

Disbursement: The paying out of funds from an acquirer to a merchant’s bank account.

Interchange fee: A fee specified by card associations that is paid by the acquirer to the issuing bank for each credit or debit card transaction. The acquirer passes this fee to merchants, in addition to any other fees charged for processing credit or debit card transactions.

If card associations find that a merchant is not PCI compliant, they can suspend the merchant’s ability to accept credit card payments and assess penalties to the merchant.
Reserve account: A portion of the funds from a high-risk (as defined by the merchant account provider) merchant's credit card transactions, held in reserve by the acquirer to cover possible disputed charges, chargeback fees, and other expenses.
Retrieval request: A request initiated by an issuing bank when a cardholder or issuing bank wants information on a credit card transaction. The merchant has a set number of days in which to respond with transaction information, or the retrieval request becomes a chargeback, in which case there is usually a retrieval request fee issued against the merchant.
SSL: Secure socket layer. A system for encrypting data sent over the Internet, including ecommerce transactions and passwords. With SSL, client and server computers exchange public keys, allowing them to encode and decode their communication.

After authorization, the merchant must submit a transaction for settlement -- this is done automatically through some payment gateways.
Void: The cancellation of the transfer of funds from the customer to the merchant. Merchants can issue a void if the transaction is either authorized or submitted for settlement.
