I read somewhere a few weeks back that a company is making SIM cards as IC chips for the "Internet of things". I can not find the article again or find anything about it on Google. Did I make this up?

This is called an e-sim or eSIM, a technology which is still not really on the market I believe, but pushed forward by IoT and giants like Apple alike. There will be SIMs in a format like DFN, possibly with support for reprogramming the carrier which is necessary for the consumer market.
