Whether use the Finnish libraries still the traditional card catalogue which would duplicate the contents of the electronic catalogue?

In Lahti City Library there is only online catalogue (no cards). We cannot say for sure what the situation is in other libraries in Finland. However, we found a figure from 2002 stating that 97% of the public libraries were computerized. You might find these links to Finnish library information useful:
