Secure Credit Card Processing Services

I am helping company to find bank that is provides Credit Card Processing Services. We starting to set up our online store soon, this are one of the plans for our company expanding the business. I am currently looking at the information I found online regarding the Provider of Merchant Accounts. I have to find a company offers Lowest Rate Billing Payment Solutions, so that we could save more.

Beside that, my boss has told me to check the company background and the system they using too. We are trying our best to avoid any complication when customer makes them payment online. We need something that is low fees but most secure system.
