I had never seen or heard of such a device so when I saw one I had to buy it and see how it worked. I got it at a used equipment sale and nobody knew what it was. Some google-fu turned up this article from 1990 which makes me think it was used in a grocery store in the 1990s and they never took off due to cost or liability reasons.
