I'm not sure this is true though. As said elsewhere in these comments, the full-keyboard version of this machine is fairly new (last 5-10 years to my memory). It used to just be an up/down arrow for adjusting how much time you wanted, and then it printed a sticker to add to your car window. The new version with the full keyboard is so they can just drive by and scan your license plate and ticket you that way if you overstay your payment. It's not like these are machines from the 90s when not that many people had computers. The addition of the keyboard is specifically something that was done because wireless internet and computer vision improved enough to do away wit the older version. I'd be earnestly curious what percentage of the population that lives in an area with controlled parking like this doesn't interact with a keyboard at least weekly. Even my 99 year old grandfather was sending emails from his computer a decade ago from his farm in the rural US. The target demographic here is A. People who own cars B. who need to park them in urban areas with street parking. Both of those are, for the last decade, likely to own a smartphone, I'd imagine.
