In my area, "way back when" means about 10 or so years ago. The local county switched to small touch screen computers containing the voting lists upon which they 'check off' that you have voted. But, the "splitting" of the lists into one per polling place likely still occurs, because it avoids a need to build a centralized database connected to all polling places to provide the "locking" necessary to allow John Smith III to vote only once. And this central system, were it to be used, also becomes a single point of failure that could halt voting at all polling places at once. Now, granted, there is still the issue of the fact that a computerized "check off" system can have records be "reset" to allow John Smith III to vote more than once in the same polling place. Paper with an ink pen line (assuming a non-erasable ink) is by far more difficult to "reset" to "not yet voted" status for John Smith III.
