New regulations require that this billing information
be passed back with the transactions, otherwise

they should have paid on retail and what they
actually qualified for (card not present). This
difference is called non-qualified interchange
fees.
PC Software:

A software program that is designed to perform
a specific function on a computer system. Examples

application and the processor. This company authorizes
and captures credit card transactions.
Procurement/Purchasing Cards:

Charge cards used by businesses to cover purchasing
expenses, such as raw materials or office supplies.
Reserve Account 
One method that ACH Processor's use to mitigate
risk, is to require that merchants maintain a
Reserve Account at the Processor's Sponsoring
Bank. This allows the Processor to issue a Hold
on funds in this account when fraud has been detected
or an excessively large number of returns is received.
Merchants with good credit and history can usually
meet the expectations of ACH Processors for covering
returns and so are not always required to keep
a reserve account. In cases where a reserve is
required, the minimum-reserve-balance in the account
is set at about 20% of the anticipated processing
volume. New merchants are usually allowed to build
up their reserve by sending in transactions which
are not withdrawn until the minimum reserve balance
is achieved; after that, the merchant is allowed
to withdraw the excess funds for transfer to their
home town bank.
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

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.
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) and then bills the cardholder. For bankcards,
the acquirer pays the merchant (less applicable
fees) with funds from Visa/MasterCard. The bankcard
issuer then bills the cardholder for the amount
of the sale. Also see Capture.
Shopping Cart Software:
- These applications typically provide a means
of capturing a client’s Credit Card information,
but they rely on the Software Module of the
Secure Gateway Provider, in conjunction with
the Secure Payment Gateway, in order to conduct
secure Credit Card transactions online.
- Any given shopping cart can work with any
given Secure Gateway Provider, the only requirement
being that some computer code be written or
provided to communicate with the Secure Gateway
of choice, and that this code be integrated
into the Shopping Cart Application.
