DALLAS – The $79 million Woodlawn Auto Workers FCU, the $95 million PCM Employees Credit Union, and the $94 million Moog Employees FCU have all moved their card processing from other processors to TNB Card Services, the card processing arm of credit union-owned Town North Bank announced. A fourth credit union, the $230 million United SA FCU, has begun a card program with TNB even though the CU is 50 years old, the processor announced. TNB would not identify the processors from which the three CUs switched. United SA FCU used to serve only the employees of the USAA insurance group but obtained a community charter for all of Bexar County, Texas, in May 2005. The community charter in turn drove the need for the card program. "We wanted to be more competitive, to offer a full set of products," explained Karla Sarran, marketing director for the credit union. United SA decided on TNB on a price basis and because it is owned by CUs, Sarran said.
