Most European countries offer some kind of government issued digital ID to their citizens, although adoption varies by country. I know two implementations first-hand and use them regularly. They work really well to prove your identity over the Internet. You can use it to open a bank account or use government services.

The next step will be EU-DI, an app based wallet with many more features and hopefully better interoperability between EU countries.
