こちらは交通系ICカード専用でして…。隣の自販機は現金も使えますよ。
こちらはこうつうけいアイシーカードせんようでして…。となりのじはんきはげんきんもつかえますよ。
This one is exclusively for public transport IC cards... The vending machine next to it accepts cash too.
Gesture & etiquette
Point to the payment slot of the vending machine while asking.
Do not try to force cash into a machine clearly marked as IC card only. Look for alternative payment options or another machine.
