Electronic Data Systems Corp. has promoted Martha Hulse to head its Card Processing Services unit.

Ms. Hulse, whose title is vice president of electronic business, was previously the service and technical delivery manager for the unit.

She will oversee the 400-member division, which processes credit card transactions for 35 million cardholders and 1.8 million merchant locations in 21 countries.

EDS has been trying to expand its card processing business, focusing mostly on international opportunities.

Ms. Hulse managed an ATM network at MTech Corp., a Dallas-based data processing firm, before EDS acquired that company in 1988. She later led point of sale and merchant business activities for EDS.
