Story highlights People arriving in Sweden by train, car and ferry to face ID checks at border

Policy is intended to help slow down the flow of people seeking refuge in the country

(CNN) Sweden has begun carrying out identity checks on commuters arriving from Denmark and Germany in an attempt to slow down the number of refugees claiming asylum in the country.

Until this week, travelers have been able to enter Sweden freely by train, car and ferry across the Danish border.

Now they will have to disembark and show their driver's license or passport before being allowed to continue their journey. Anyone without a valid form of ID will be turned back.

The new policy caused some delays early Monday, particularly for commuters who live in Sweden and work in neighboring Denmark -- nearly 75,000 people a day cross the Oresund bridge between the two countries -- but fears of traffic chaos and a backlog of refugees did not materialize.
