A small Atlanta-based payment processor announced on Tuesday it has merged with an Oklahoma-based firm.

Terms of the merger between Capital Payments LLC and Tulsa-based Bluefin Payment Systems were not disclosed.

Capital Payments will be the surviving company, and will add technical and sales staff in Atlanta, Tulsa and New York, Capital Payments President and CEO John Perry said in an email.

Bluefin focuses on secure payments technology, including applications for mobile payments, according to a news release. The company serves firms in the faith-based, education, insurance and non-profit sectors.

Capital Payments serves merchants in the U.S. and Canada, providing debit and credit card processing, among other services.
