If you need to accept credit cards for your business, you have to deal with the acquiring bank. It is common for the responsibilities of the acquiring bank to be split between two entities. The first, commonly called
the merchant service provider, is in constant contact with the merchant.
When a sales representative shows up at your door to try to sign you up for credit card processing, or when you interact with a Web site (you may find many companies to consider) you are dealing with the merchant service provider, which can be an arm of a bank or a smaller independent company.
Partnering with a company like Quantum will give you complete coverage. You will be able to accept any major credit card and you will have an award winning customer service contact at your disposal 7 days a week.
