Don't know about the whole Europe (or EU) but I strongly suspect it is indeed (almost) everywhere. I'm Turkish and Turkey has it too. And yes, my mother uses it, and my grandparents used it when they were alive. You can't do anything government-related, open a bank account, or even visit a hospital without your government-issued ID card (which contains a chip). And a few decades ago, before the chips, there were other security measures tied to ID cards.
