Money Access Service Inc. reported processing a record 109 million transactions for its MAC network in May.

Philip A. Valvardi, president of MAC, said new automated teller machine deployments, especially at sites away from bank premises, are driving the growth of volume through the MAC switch.

Off-premises ATMs, which tend to have lower volumes than those at bank branches, have become more attractive to banks and other operators with the surcharges they are now allowed to impose on noncustomers.

MAC, which is owned by Electronic Payment Services Inc., is the perennial leader in switch transactions.

Those volumes have been topping 100 million since March-about 40 million more than in the No. 2 regional network by this measure, Star System Inc. of San Diego.
