Switzerland has its own currency and its own central bank. It doesn't use the Euro. So the money doesn't need to 'paid for'. The government can just create the money and hand it out.
Of course this might devalue the currency as a whole, but the central bank had to institute an exchange rate floor because Francs were becoming too expensive relative to the Euro. So they probably wouldn't even consider a minor devaluation a bad thing.
