In the case of Suica, there are some stations where the card can't be recharged by credit cards (the credit cards are accepted only in the JR West ICOCA Area, and in the JR East Suica Area, the View Card issued by JR East is the sole credit card accepted).
Suicaの場合、一部の駅（ICOCAエリアのみでSuicaエリアではJR東日本のビューカードのみ）ではクレジットカードでのチャージができない駅もある。
