Italian ID cards too, as well as the owner's signature, the fiscal code (an unique identification code similar to the SSN in the USA) and the fingerprints (though these latter are stored in the chip only, not printed on the card).

It's very likely that this data is also stored in some government database, which I hope will never get breached.

Nitpick (as you well know) - codice fiscale in Italy differs from USA SSN in that, for once, it has never had AFAIK any semblance of secrecy at all, as you can easily construct it starting from name, surname, place and date of birth [1] Funnily enough, this sometimes results in two individuals computing to the same code [2]
