The IC card system and how it became what it is today is a _fascinating_ topic, tied deeply with the superb automated gates at Japanese train stations in. I wonder if people would be interested in reading a longform-ish piece on these..

I mean, people enjoyed this piece on HN a bit ago, so I'm sure there's an audience. https://news.ycombinator.com/item?id=30228327

I'm in OT and deal with train and airplane tech. Would definitely be interested.
