Credit Card Processing: Terms & Definitions

As with any specialized field, credit card processing uses a number of terms whose definitions may be unfamiliar to the uninitiated. But there’s no need to cringe when reading your contract or talking with your service provider. Here is some quick help for some of the most common terms you will come across:

Acquiring bank – The bank that processes the credit card transaction and deposits the money from the customer’s bank account into the merchant’s bank account (or vice versa during a chargeback). Also called the “clearinghouse bank.”
