Well being that I am a Diebold ATM tech charged with installing new atms, upgrading them with the triple Des keypads, and other troubleshooting; I have to recommend Diebold. Ncr machines have a vacuum type picking system that is questionable in its performance, while Diebold ATMs use a series of belts and motors. Belts and motors are very easy to replace. Many of the new ATMs that I install are replacing NCRs. With the new Optivas, I can understand: Clean modern design, Better consumer screen visibility, up to 5 cassetes, faster transaction processing, Rear Balancing capabilities, electronic data capture. Best of all Diebold is made in America while NCR is assembled in Canada.
