It not necessary will cost money, in Malaysia it is free. United Kingdom and United States ask indeed some money for it.
Other European countries don't have such a system yet.
It is just changing the moment they register you, so the level of controlling your movements do not really change.
When I see how many "so called tourists" do use the visa exemption system meant for tourists, I can understand Thailand wants to control this better.
If this really will work is just another thing.
