Glossary of Terms
Navigating through a sea of technical terms, phrases, and acronyms can be confusing, even for someone familiar with the payment processing industry. Here is a list of some of the most commonly used payment processing terms to help you.
A unique sequence of numbers assigned to a cardholder account that identifies the issuer and type of financial transaction card.
A tool that, in conjunction with tokenization, automatically keeps credit cards in the Cardknox data vault updated to ensure subsequent transactions are not declined.
Automated Clearing House – Electronic network used to transfer money and payment information between bank accounts. See https://www.cardknox.com/ach for more information.
A licensed member that maintains the merchant relationship and acquires the data relating to a transaction from the merchant or card acceptor and submits that data into interchange, either directly or indirectly.
Automatic Funds Transfer – A transaction in which funds are securely transferred from one bank account to another via electronic or telecommunications technology.
Anti-Money Laundering – A set of laws, regulations, and procedures intended to prevent criminals from disguising illegally obtained funds as legitimate income. See KYC for more information.
A yearly fee charged by some independent sales organizations (ISOs) and acquirers to maintain a merchant’s account. This is also called a renewal fee, subscription fee, or membership fee.
Application Programming Interface – A technological interface or communication protocol between a client and a server intended to simplify the building of client-side software. See https://www.cardknox.com/features-cardknox/ for more information.

A process defined in operations regulations whereby a transaction is approved by or on behalf of an issuer; commonly understood to be receiving of a sales validation by the merchant, telephone, or authorization terminal.
A code notifying you that you have obtained the authorization for a specific card transaction.
Address Verification System – Also referred to as Address Verification Service, AVS is a system used to verify whether the billing address given by the customer matches the credit card used for the transaction. This system checks the billing address of the credit card provided by the user with the address on file at the credit card company. If a merchant chooses not to use AVS, Visa and Mastercard will not support their transactions and will charge an additional percentage on those sales.
Cardknox feature that enables the AVS response to occur before the authorization so that if the transaction is declined, there is no temporary hold on the customer’s card.
A debit or credit card issued by an issuing bank. Also referred to as “bankcard.”
A collection of credit card transactions saved for submitting at one time, usually each day. Merchants who do not have real-time verification systems must submit their transactions manually through a point-of-sale (POS) terminal. Batch fees are charged to encourage a merchant to submit his or her transactions at one time, rather than throughout the day.
Browser-Based POS – Cardknox application that allows a POS running in a browser to accept EMV payments while remaining out of PCI scope.
The interval between periodic billings for goods sold or services rendered, typically sent on a monthly basis.
Bank Identification Number – The first 6 digits of a credit or debit card number. Also referred to as Issuer Identification Number (IIN)
A payment card industry governing body that sets rules and interchange rates. Visa, Mastercard, Discover, and American Express are the four largest card associations in North America.
The customer to whom a card has been issued, or the individual authorized to use the card.
A chargeback occurs when a cardholder disputes a credit card transaction with his or her credit card issuer. The card issuer initiates a chargeback against the merchant account. The amount of the disputed transaction is immediately withdrawn from the merchant’s bank account, and the merchant has 10 days in which to dispute the chargeback with supporting documentation such as proof of purchase, customer signature, proof of delivery, etc. A chargeback is ultimately decided and resolved by the card association. A chargeback fee is usually assessed to the merchant on top of the actual transaction. See also Retrieval request.

A payment method that uses near field communication (NFC) technology to enable purchases using an NFC-enabled EMV chip card, or other payment-enabled device such as a mobile phone, at the point of sale without having physical contact with the payment terminal. See NFC for more information.
A refund or return of goods by a consumer to the merchant.
A transaction card bearing an account number assigned to a cardholder with a credit limit that can be used to purchase goods and services and to obtain cash disbursements on credit.

The currency of transaction is determined by the acquirer; the currency of the issuer is the preferred currency used by the issuer, and most often, the currency in which the cardholder will be billed.
Card Verification Value – Security feature used with card-not-present transactions. The CVV is a 3- or 4-digit code either printed or embossed on a credit or debit card. Also known as Card Security Code (CSC). Issuer variations:

Dynamic Currency Conversion – A credit card processing solution that allows merchants to offer international customers the choice to pay with Visa and Mastercard in either their local currency, or the merchant’s base currency.
The exchange rate includes a 3% margin which is displayed on the receipt along with the conversion. By paying in their local currency, tourists and business travelers can make informed decisions about their purchases and feel confident knowing the exact amount they are paying. In addition, cardholders have the choice of opting out and paying without converting the sale to avoid being charged international fees when their issuer does not charge.
