Glossary of Terms For The Electronic Payment Processing Industry A B C D E F G H I J K L M N O P Q R S T U V W X Y Z ABA The American Banking Association (ABA) routing number is a unique, bank-identifying number that directs electronic ACH deposits to the proper bank. This number precedes the account number printed at the bottom of a check and is usually printed with magnetic ink. Account Number A unique sequence of numbers assigned to a cardholder account which identifies the issuer and type of financial transaction card. ACH See Automated Clearing House. Acquirer A bank or financial institution that issues merchant accounts for the acceptance of credit card transactions. Acquiring Bank The bank that maintains the merchant relationship and receives all transactions from the merchant. Address Verification Service A service that verifies the cardholder's billing address in order to help combat fraud in card-not-present transactions (e.g. mail order, telephone order, internet, etc.). Used only in the United States. Agent Bank A bank that participates in another bank's acquiring program, usually by turning over its applicants for bank cards to the bank administering the bank acquiring program. American Express An organization that issues cards and acquires transactions, unlike Visa and MasterCard, which are bank associations. AmEx See American Express. API The Application Programming Interface (API) is the interface by which an application program accesses the operating system and other services. An API is defined at source code level and provides a level of abstraction between the application and the kernel to ensure the portability of the code. Approval Any transaction that is approved by the cardholder or check writer's bank. Approvals are requested via an authorization. An approval is the opposite of a declined transaction. Arbitration The procedure used to determine the responsibility for a chargeback-related dispute between two members. Asynchronous A method of transmitting data in which the data elements are identified with special start and stop characters. An asynchronous modem cannot communicate with a synchronous modem. Compare with Synchronous (e.g. standard Hayes compatible modem). Auth Only A transaction in which the merchant does not intend to capture funds until a later time, if at all. See Prior Authorized Sale. Authorization An authorization is a request to charge a cardholder. It reduces the cardholder's open-to-buy but does not actually capture the funds. An authorization is the first transaction in the delayed settlement process. It does not bill the card until a delayed capture transaction is issued. The authorization must be settled in order to charge the account. If it is not used within a certain time period, it will drop off. The issuing bank determines the time period for drop off. Authorizations can only be used for credit card transactions. Authorization Code Approved sale and authorization transactions always receive a numeric or alphanumeric authorization code that references the transaction for processing purposes. Automated Clearing House The Automated Clearing House (ACH) network is a nationwide, wholesale electronic payment and collection system. It is a method of transferring funds between banks via the Federal Reserve System. It is used by most, but not all, financial institutions. Average Ticket The average dollar amount of merchant credit transactions. AVS See Address Verification Service. Back to Top Bank Identification Number The digits of a credit card that identify the issuing bank. It is sometimes the first six digits and is often referred to as a BIN. Basis Point One one-hundredth of a percent. Discount rates are expressed as basis points. Batch A collection of transactions submitted for settlement. Usually a merchant has one batch per day or per shift. Batch ID Once a batch is settled, it receives a batch ID. Every transaction in the batch shares this ID. If a transaction does not have a batch ID associated with it, the transaction has not been settled. Batch Processing A type of data processing where related transactions are transmitted as a group for processing. Batch Settlement A sort of electronic bookkeeping procedure that causes all funds from captured transactions to be routed to the merchant's acquiring bank for deposit. Signio automatically submits all captured transactions for settlement on a daily basis. The time that it takes for these funds to reach the merchant account after settlement is 1-5 days, but varies by acquiring bank. BIN See Bank Identification Number. Binary Executable A universal character-coding system. Bundled Rate A discount rate that includes communications costs as well as transaction fees. Also referred to as a flat rate. Back to Top Capture The process of capturing funds from an authorization. Card Issuer See Issuer, Issuing Bank.

The service determines whether the check writer has previously written delinquent checks. Companies like TeleCheck provide this type of service. Clearing The process of exchanging financial details between an acquirer and an issuer to facilitate posting of a cardholder's account and reconciliation of a merchant's settlement position. Common Gateway Interface An interface program that enables an Internet server to run external programs to perform a specific function. Also referred to as gateways or CGI scripts, these programs generally consist of a set of instructions written in a programming language like C or PERL that process requests from a browser, execute a program and format the results in HTML so they can be displayed in the browser. Gateway scripts often add interactivity to a web page by enabling users to fill out and submit forms for processing. Confirmation Letter A letter sent by a processor to a merchant on a daily or weekly basis to verify batch deposits. Copy Request See Retrieval Request Credit A credit is a Signio transaction type that transfers funds from the merchant's account back to a customer's credit card.

Delayed Capture A delayed capture is a transaction type that uses the information from an authorization transaction to capture funds.

This procedure is recommended when the merchant delivers goods or services more than 48 hours after they are ordered.
