Acquiring Bank
The bank or financial institution that accepts credit and/or debit card payments for products or services on behalf of a merchant.

Acquiring Processor
Provides credit card processing, billing, reporting, settlement and operational service to the merchant on behalf of the acquiring and issuing banks. Many financial institutions hire a third party for more cost‐effective bankcard processing.

ABA Routing Number
The nine-digit number assigned to individual banks to identify them.

Address Verification Service (AVS)
A system used to verify the identity of the person using the credit card. The system will check the stated billing address of the card against the one on file with the issuer. The response provides an AVS code in each approved transaction result that tells you how well the two addresses match. Merchants can use AVS codes to help protect themselves from potential Chargebacks and fraud.

Application Programming Interface (API)
Software used by an application program to request and carry out lower‐level services performed by a computer’s or telephone system’s operating system. API allows a merchant to add payment functionality to custom built websites or online applications.

Approval Code

The act of ensuring the cardholder has adequate funds available against his or her line of credit at the time the authorization was requested. A positive authorization results in an authorization code being generated and those funds being set aside. The cardholder’s available credit limit is reduced by the authorized amount.

Automated Response Unit (ARU)
Allows the manually keyed entry and the subsequent authorization of a credit card transaction over a traditional landline telephone or cell phone service. Please visit Merchant Resources.

A group of approved and accumulated credit card sales and credit transactions that have been captured but not yet settled. Most merchants settle or close their batches at the end of each day.

Batch Deposit

Business to Business (B2B)
One business communicating with or selling goods and/or services directly to another business. This merchant category is different from retail where a business typically does business directly with consumers.

Card Code (CVV2)
The card security code, sometimes called Card Verification Value or Code (CVV or CVC) or Credit Card ID (CCID). It is a security feature for credit or debit card transactions giving increased protection against credit card fraud. This code is often asked for by merchants to secure a transaction when the card is not present (CNP). These sales usually occur over the Internet, by mail, fax, or over the telephone. The payment gateway will compare the card code with the code on file at the card‐issuing bank. Results of this comparison will show in the transaction approval code. By using the card code results along with the Address Verification Service (AVS), you can make a more informed decision about whether to accept transactions. MasterCard®, Visa®, and Discover® have a three‐digit code on the back signature panel of the card. American Express cards have a four‐digit code printed on the front side of the card above the number.

Card Not Present (CNP)
Any number of payment transactions in which cards are not tendered. The card information is manually entered by the customer (online) or merchant over the telephone. These sales carry a higher risk and therefore are assessed a higher Interchange rate.

Card Organizations
Any entity formed to administer and promote Cards. The Card Organizations charge the Acquires interchange fees and assessment for submitting transactions into their systems. A substantial portion of the Discount Rate or Transaction Fees merchants pay will go towards these fees and assessments. Each Card Organization has developed Card Organization Rules that govern their Acquirers and Issuers and the procedures, responsibilities and allocation of risk for this process. Merchants are also bound by Card Organization Rules.

Card Present
A type of transaction in which the card is present and is typically swiped through an electronic device that reads the contents of the magnetic stripe on the back of the card.

A reversal of a credit card transaction (or a disputed portion) initiated by the card issuer at the cardholder’s request. Chargebacks can occur for any number of reasons including; customer disputes, potential or actual fraud (on the part of merchants, sales associates and/or customers), processing errors and authorization issues. Chargebacks are governed by a complex set of rules and time limits that can be costly to merchants and their banks if disregarded.

Today the majority of credit card transactions are sent electronically to merchant processing banks for authorization, capture and deposit.

Doing Business As (DBA)
The name an individual, company or organization chooses to conduct business under other than their legal or registered name.

Occurs when the merchant does not meet the Visa®/MasterCard® requirements for a transaction and, as a result, the transaction is moved to a lower level and more costly rate of Interchange pricing.

Consists of the buying and selling of products or services over electronic systems, such as the Internet and other computer networks (electronic commerce).

Electronic Benefit Transfer (EBT)
An electronic system that allow a government benefit recipient to authorize the transfer of their benefits from a federal, state or local government account to a merchant account to pay for products and services received.

Electronic Funds Transfer (EFT)
A transfer of funds between one account and to another by electronic means rather than conventional paper‐based payment methods. EFT transactions can originate from a telephone, IP or electronic terminal, or from a computer or magnetic tape.

Electronic Ticket Capture (ETC)
A system that reaches out and “grabs” sales ticket information electronically. As the customer “swipes” or key enters a credit or debit card through a terminal the account information contained on the magnetic strip is read by the computer system and merged with the sales information. This information is then encoded and electronically sent to the processing system when the merchant closes the batch of transactions at the end of the day.

The technique of scrambling data automatically in the terminal or computer before data is transmitted for security/anti‐fraud purposes.

Face‐To‐Face (Card Present)
Transactions that take place with the cardholder and merchant face‐to‐face. The cardholder typically swipes the card in a terminal. This type of transaction has the ability to qualify for a lower Interchange rate as it is considered low risk.
