No fucking computers. If you mean the old fashioned mechanical tabulators that accountants use to use, then that’s a conversation. But nothing electronic. So easy to sneak a full PC inside since the electronics can be smaller than your pinky nail and use the display to feed the fraud.

The only internet access should be for the webcams watching down on the counters so you can follow along as they count. These videos should be stored for no less than a thousand years. Any attempt at interfering with the feed or deleting the videos should be treated as treason.
