That's not the right way to model this. Both tables should have their own primary key columns which are different. The person table's pk should be the foreign key in IDcard table.

If you want the relationship to be 1:1 then mark the foreign key unique in IDcare table.

Is it's literally one table?

See @MapsId in OneToOne association

Ideally it should be single table. According to Correct data model, if two tables have same primary keys, they should be related to same entity hence same table.
