A
Acceptor:
A business that has qualified to accept credit or debit cards as payment.
Acquirer:
An acquirer is an organization licensed as a member of Visa / MasterCard as an affiliated
bank or bank/processor alliance that is in the business of processing credit card
transactions for businesses (acceptors) and is always acquiring new merchants.
Acquiring Financial Institution:
An acquiring financial institution (or "acquirer") contracts with the
bank and merchants to enable credit card transactions. The acquirer deposits the
daily credit card totals and debits the end-of-month processing fees from the merchants'
accounts.
Address Verification Service (AVS):
The process of validating a cardholder's given address against the issuer's records,
to determine accuracy and deter fraud. This service is provided as part of a credit
card authorization for mail order/telephone order transactions. A code is returned
with the authorization result that indicates the level of accuracy of the address
match and helps secure the most favorable interchange rates.
Adjustment:
An adjustment is initiated by the acquirer to correct a processing error. The error
could be a duplication of a transaction or the result of a cardholder dispute. The
acquirer debits or credits the merchant's DDA account for the dollar amount of the
adjustment.
Assessments:
Assessments are processing fees merchants pay to the Card Associations to finance
their roles in operating the network, setting rules, setting pricing, research and
development, and marketing/branding. They are a set percentage of the sale and are
generally collected on a daily or monthly basis.
Associations:
Any entity formed to administer and promote credit and cards. The best known examples
of Associations are MasterCard and Visa.
Audio Response Unit (ARU):
This is an electronic authorization and capture product where the merchant uses
a touch-tone telephone to process transactions.
Authorization:
The process of verifying that the credit card has sufficient funds (credit) available
to cover the amount of the transaction. An authorization is obtained for every sale.
An approval response in the form of a code sent to a merchant's POS equipment (usually
a terminal) from a card issuing financial institution that verifies availability
of credit or funds in the cardholder account to make the purchase. Also see Point-Of-Sale.
Authorization Response:
An issuing financial institution's electronic message reply to an authorization
request, which may include:
* Approval -- transaction was approved
* Decline -- transaction was not approved
* Call Center -- response pending more information, merchant must call the toll-free
authorization phone number.
Authorization Code:
A code that a credit card issuing bank returns in an electronic message to the merchant's
POS equipment that indicates approval of the transaction. The code serves as proof
of authorization.
Auto Close:
A terminal feature that allows an end-of-day batch closing to occur automatically
at a specified time, without having to be initiated by the merchant.
Automated Clearing House (ACH) File:
A file with instructions for the exchange and settlement of electronic payments
passed between financial institutions. It represents debits and credits to be deducted
from an account automatically as they occur.

is calculated by dividing the total sales volume by the total number of sales for
the specified time period.
B
Bankcard:
A credit card issued by a Visa or MasterCard-sponsored financial institution. (American
Express, Discover, Diners Club, JCB, etc., are issued directly from their respective
operations, rather than through banks.)

Customer to whom a card is issued or individual authorized to use the card
Cardholder data:
Full magnetic stripe or the PAN plus any of the following:
* Cardholder name
* Expiration date
* Service Code
Cardholder data environment:
Area of computer system network that possesses cardholder data or sensitive
authentication data and those systems and segments that directly attach or
support cardholder processing, storage, or transmission. Adequate network
segmentation, which isolates systems that store, process, or transmit cardholder
data from those that do not, may reduce the scope of the cardholder data
environment and thus the scope of the PCI assessment.
Card Issuing Bank:
An EFT Network Member-Bank that runs a credit card or debit card "purchasing
service" for their account holders. An example is CitiBank and the CitiBank
Visa Card that they issue.
Card Not Present:
A transaction where the card is not present at the time of the transaction (such
as mail order or telephone order). Credit card data is manually entered into the
terminal, as opposed to swiping a card's magnetic stripe through the terminal.
Chargeback:
A credit card transaction that is billed back to the merchant after the sale has
been settled. Chargebacks are initiated by the card issuer on behalf of the cardholder.
Typical cardholder disputes involve product delivery failure or product/service
dissatisfaction. Cardholders are urged to try to obtain satisfaction from the merchant
before disputing the bill with the credit card issuer.

now have special procedures for passing billing information back to the card issuing
bank so that it can be displayed on card holder statements; this is a program for
promoting the use of credit cards for business purchases by providing purchase tracking
to business users. New regulations require that this billing information be passed
back with the transactions, otherwise a higher pass through fee will be incurred.
Compensating controls:
Compensating controls may be considered when an entity cannot meet a requirement
explicitly as stated, due to legitimate technical or documented business constraints but
has sufficiently mitigated the risk associated with the requirement through implementation
of other controls. Compensating controls must 1) meet the intent and rigor of the original
stated PCI DSS requirement; 2) repel a compromise attempt with similar force; 3) be above
and beyond other PCI DSS requirements (not simply in compliance with other PCI DSS
requirements); and 4) be commensurate with the additional risk imposed by not adhering
to the PCI DSS requirement.
Compromise:
Intrusion into computer system where unauthorized disclosure, modification, or
destruction of cardholder data is suspected.
Corporate Card:
Charge card designed for business-related expenses, such as travel and entertainment.
Please see Commercial Card.
Credit (Reversal):
Nullification of an authorized transaction (sale) that has not been settled. If

A fee paid by an acquirer to an issuer for transactions entered into interchange.
The interchange fee is a percentage applied, according to Visa/MasterCard regulations,
to the dollar value of each transaction. There are multiple categories of interchange,
and Visa and MasterCard each have their own criteria for their own categories. A
transaction must meet the specified criteria for a category in order for that category's
rate to be applied. Each transaction is evaluated individually, so various interchange
rates may apply within one batch of merchant transactions.
Internet Service Provider (ISP):
Internet Service Providers (ISPs) are the Website Hosting companies that provide

N
Network:
Company and system used to authorize and capture credit card transactions.
Non-Qualified Transaction Fees (Non-Qual):
Bankcard sales transactions that do not meet set Visa/MasterCard criteria for that
particular merchant and are processed at a higher interchange rate. An example of
this is a merchant that is retail (card present) that processes a card-not-present
transaction (or manually enters card data rather than swiping the magnetic stripe
through the terminal). The merchant will pay the difference between what they should
have paid on retail and what they actually qualified for (card not present). This
difference is called non-qualified interchange fees.

P
PA:
Payment Applications
Payment Application Data Security Standards (PA-DSS):
The goal of PA-DSS is to help software vendors and others develop secure payment applications that do not store prohibited data.
PCI:
Payment Card Industry
Payment Card Industry Data Security Standards (PCI DSS):
The PCI DSS is a multifaceted security standard that includes requirements for security management, policies, procedures.
PC Software:
A software program that is designed to perform a specific function on a computer
system. Examples would be accounting systems, manufacturing systems, order entry
and fulfillment, ticketing, reservations, etc. The application is either purchased
or built by the merchant, and must be interfaced with a credit card authorization
system in order to provide on-line transaction processing.
PCI Compliance:
PCI Compliance refers to industry-mandated security standards that apply to all
businesses that handle, process or store credit or debit cards. The three PCI
compliance standards are PCI DSS, PA-DSS and the PCI PED.
PCI Compliance Deadlines:
Deadlines for merchants, service providers and software applications to be
compliant with the corresponding PCI standard.

Q
R
Real-Time Processing:
Real-Time Processing means that when a web site's customer conducts an online purchase,
that the check or credit card information is conveyed to the Processor at that exact
time so that an authorization can be requested and received at that moment. Real-Time
Processing always implies that a Secure Payment Gateway is being utilized, whether
proprietary or third party. Please see Secure Payment Gateways and Real Versus Non-Real
Time Processing.
Recurring Billing:
A tool for submitting and managing recurring or subscription-based, transactions.
S
Sales Draft (Ticket):
A form showing an obligation on the cardholder's part to pay money (i.e., the sales
amount) to the card issuer. This is the piece of paper that is signed when making
the purchase. Sales draft data can be captured electronically and sent to be processed
over the phone lines. Also see Electronic Data Capture.
Secure Payment Gateway:
Secure Payment Gateway companies help other processors conduct secure business on
the internet using Secure Socket Layer (SSL) technology.
-They provide a system that passes credit card data, authorization requests, and
authorization responses over the internet using encryption technology.
-The transaction information is sent by the payment gateway secure server via leased
line to the credit card network where the validity of the card is checked and the
availability of funds on that account is verified. An authorization code is returned
via leased line to the payment gateway; the authorization is encrypted by the payment
gateway and transmitted in encrypted form to the web server of the merchant, which
triggers fulfillment of the order.
-Rather than try and create their own Secure Web System, many banks and bank/processor
alliances will use a Secure Payment Gateway Provider to perform this task for them.
Settlement:
The process of sending a merchant's batch to the network for processing and payment.
For non-bankcards, the issuer pays the merchant directly (less applicable fees)

of Point Of Sale (POS) terminals connected to their Host via dial out modem; they
produce the software in the POS terminals as well as in their host, and route authorization
requests to Visa or MasterCard as needed (MAPP, MDI, FDR, for example).
-Other Third Party Processors specialize in the Settlement of credit card transactions
with Visa and MasterCard so that merchants can be paid (FDR for example).
