The yellow Health Care Card
Every Dane has a health care card, a little yellow plastic card with a magnetic field on the back side, containing information of identity. The card can be used for several things, first of all as registration at doctors or hospitals before medical treatment, (which is free), but also as at the library when borrowing books or as an easy way to register when such is needed. The yellow card can also be used as documentation to show that Danes are insured -in some specified cases-, when traveling less than a month in EU and some other countries. There is a blue card for travels which last longer, up to one year.
