### 4/5 — カードによって

*2026-08-03*

2007年に購入したT moneyカードの残高を読み取ることができました。助かります。
念のために、2011年に購入してずっと使っていなかったものもやってみましたが、こちらは「このカードはサポートされていません」と表示されて、読み取れませんでした。
こちらは、全然使っていなかったからでしょうか？

*2025-07-18*

허…라는 소리만 나오네요.
몇달전부터 계속 썼거등여? 근데 며칠 전부터 계속 NFC에 데도 인식이 안되요. 분명 내가 NFC위치도 몇번이고 확인하면서 인식시키려 했는데…이거 뭐에요? 
카드 뭔지만 가르쳐 드릴게요. 카벵 미니 쳌카드여.

(와 와유오아이어님이랑 정확히 같은 상황을 겪고 있어요. 개선 안해요?)
