ONTARIO, Calif. - The $2 billion Digital Federal Credit Union, headquartered in Marlborough, Massachusetts, has chosen to process all of its 218,000 members' ATM transactions with the CO-OP Network, the nation's largest credit union owned surcharge free ATM network. Digital has been a member of CO-OP Network since 1998. "This is a natural progression in our relationship with CO-OP Network," said Craig Roy, a vice president with Digital. "The DCU processing agreement with another vendor recently expired, and one of the major reasons we turned to CO-OP Network is our organizations share similar ideals and values: They're a network owned by credit unions, and we're a credit union owned by our members. "Additionally, CO-OP Network is a mainstay in an industry faced with continual consolidation, and I'm confident our organizations will help each other grow and prosper in future years."
