People who buy ATMs have a strong vested interest in their security, both physical and virtual. If the machines can be broken into or hacked, the people who buy the machines lose real actual cash. If the machines merely malfunction, it upsets their customers, which then costs the machine owners.
Ultimately, you can run the numbers on security to see how much money it's worth, how much it costs, and find the ideal tradeoff.
Voting machines have completely different incentives. The buyers have no vested interest in their security whatsoever. I would actually argue that they have a bit of a vested interest in insecurity, because a successful voting machine hack would probably cost people their jobs if it came to light, and if a machine is so insecure that you can't even detect hacks then this risk goes away. And if the machines malfunction, users often can't even tell. Even if they can tell, their unhappiness typically won't financially impact the people who buy the machines.
And thus we can see why, for example, Diebold builds good ATMs but craptastic voting machines.
