Starting a business today can be very difficult at times. You might come across words or terms that you might not understand, especially if you are starting an online business (or e-commerce).
One of the first things that you might want to do is accept credit cards at your place of business or online. This is called a merchant account. Basically, there are two types - swiped (for brick and mortar business) and keyed (for Internet businesses or telephone orders). An Internet merchant account costs a bit more money in terms of a discount rate because the risks of chargebacks is higher than a brick and mortar business. A good place to start is Some Basic Merchant Account Fees - this post will help explain some of the terminology that you might run into.
A merchant account for brick and mortar businesses can differ from merchant account provider to another.
