Interesting fact. I thought that having an ID card is pretty much mandatory in whole EU. In Slovakia you get one at age of 15 (I think) and it has biometric data - picture and fingerprints. You are not required by law to carry it with you, but it can cause delays if need to be verified by police or other authority. It’s also used to login into e-gov services with a card reader and your pin - but it’s quite limited at this point.
