There are no border controls between countries that have signed the Schengen Agreement. Likewise, a visa granted for any Schengen Agreement signatory country is valid in all other countries that signed the treaty.
These countries are: Austria, Belgium, Denmark, France, Finland, Germany, Greece, Iceland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Spain and Sweden. Note that not all EU members have signed the Schengen treaty and not all Schengen treaty countries are members of the European Union.
At some airports, airlines will still insist on seeing your id-card or passport. Travel to and from a Schengen Agreement country to any other country will result in the normal border checks.
