This page provides details on ShopSite credit card processing. The basic process is described in Credit Card Processing in ShopSite, but we thought we'd give you the whole story in case you're curious.
If you've only been a shopper before and never a retail merchant, you might be very surprised to know the number of parties involved in a credit card transaction.
The bank which approves a merchant for accepting credit cards, and then collects the merchant's online payments. Some banks use Independent Sales Organizations to be the front-end of this service. Acquiring Banks are generally members of the Visa and MasterCard Associations
Visa and MasterCard are actually associations of member banks and financial institutions. The associations specify membership rules, but do not issue credit cards; the members issue the cards. American Express, Discover, and Diner's Club are single corporations and not associations, and they issue their own cards.
The cardholder is, of course, the customer - someone who an issuing bank deems trustworthy enough to extend some credit to.
Independent Sales Organization (ISO)
A third-party company that provides services to merchants on behalf of the acquiring bank. These services include merchant accounts, funds processing, and account activity reporting.
A bank or other financial institution that issues credit cards. Issuing banks are members of the Visa and MasterCard Associations.
A business that has a merchant account for accepting credit cards. Despite being called "the merchant" in the credit card industry, this term really refers to the business, not the owner (though they may be the same in the case of a sole proprietor.
A company that provides an interface between the Internet and the secure banking networks. A payment gateway authenticates the parties involved and acts as a channel for moving credit card transactions from your ShopSite store to a payment processor.
A corporation that manages the process of transferring authorized and captured credit card funds between different financial accounts.
In addition to knowing who's involved in a credit card transaction, there is also a special vocabulary that you might want to be familiar with:
Authorization - The act of ensuring that the cardholder has adequate funds available against their line of credit. A positive authorization results in an authorization code being generated, and a hold being placed on those funds. A "hold" means that the cardholder's available credit limit is reduced by the authorized amount.
Capture - Converting the authorization amount into a billable transaction record. Transactions cannot be captured unless previously authorized.
Discount Rate - A small percentage of each transaction that is withheld by the Acquiring Bank or ISO. This fee is basically what the merchant pays to be able to accept credit cards. The fee goes to the ISO (if applicable), the Acquiring Bank, and the Associations.
Merchant Account - A special business account set up to process credit card transactions. A merchant account is not a bank account (even though a bank may issue it). Rather, it is designed to 1) process credit card payments and 2) deposit the funds into your (business) checking account (minus transaction fees).
Payment Gateway Fees - The fees that payment gateways charge for their services. This generally includes a monthly fee and a small flat fee per transaction. These fees may consolidated into a single bill by the acquiring bank or ISO, along with their fees.
Transaction Fee - A small flat fee that is paid on each transaction. This fee is collected by the acquiring bank or ISO and pays for the toll-free dial out number and the processing network.
