If you want to buy a game in the Swiss PSN store from 18 you need the identity card?

I'm Thomas 15 living in Switzerland

My question is whether you have to confirm his age if you want to buy a game from 18 in the PSN store. As far as I know in Germany PSN cards are from 18 and you need an ID card in the PSN store to confirm its age if the game is over 18. Is that the same in Switzerland? The PSN card I can be without 18 to buy everywhere but if you have to confirm his age if you want to buy a game from 18 I unfortunately do not know.

Thank you for reading Would be glad about an answer.

Yes, you always have to confirm your age if you buy a game of 18 or over. The questions Badge numbers / passport numbers

Is that the case in Switzerland? Because in Ö. Not.
