The best implementation I know of digital ID is the one in Estonia. It comes with a data tracker, such that each citizen can see who exactly has been looking at their data [1].

Done more or less like that in Belgium too. Basically, if any civil servant look at your data, this is recorded in the "Banque Carrefour de la Sécurité Sociale". Your eid is used to authentify/authorize you on various state web site (which is OK)
