I moved from the UK to Scandinavia and there is a BankID system that allows you to authenticate yourself for any digital service, public or private, and it's amazing how useful that is. I work in financial services and the ability to correctly identify a new customer removes a bunch of problems that we'd have elsewhere. The flip side is that if you don't want this ID it becomes more difficult (but not impossible) to access any digital service. It also relies on an integrated public population register, which some people have problems with. But it's not a physical ID that you can be asked for or are required to have, so doesn't have the ideological & political issues of requiring a universal ID card.
