The Edmonton automated teller machine operator Cash N Go Ltd. will use processing software from S1 Corp.'s Postilion.

Cash N Go, which owns a network of over 1,200 machines, said the Norcross, Ga., vendor's software will improve its service.

"Owning and managing our own switch gives Cash N Go the flexibility and control to be more responsive to the ever-changing ATM marketplace," Ken Nichols, Cash N Go's president, said in a press release Wednesday.

Mr. Nichols also cited the software's ability to guarantee uptime.

"Cash N Go will assume responsibility for network performance, thus minimizing the challenges that are often present when having to deal with multiple vendors," he said.
