Beside all advantages of basic card the SŪ-Ej!KArtica card offers also 30 % discount on train tickets in Slovenia and 25 % discount on trains in Europe (RailPlus included in the card - more details). So, for the train tickets you need to buy a cobranded SŪ-Ej!KArtica card to receive the discount. You can buy it on any major train station only in Slovenia (see the link above for the list of railway stations). Of course you can use the SŪ-Ej!KArtica cobranded card also for other Ej!KArtica discounts all over Europe (except the ones that are included in different co-branded cards).
