What history is stored on the card
- Train rides with entry station, exit station and fare.
- Bus fares and tram fares paid with the card.
- Konbini and shop purchases such as 7 Eleven, FamilyMart and Lawson.
- Top ups done at station machines.
Japanese IC cards store the last 20 or so transactions on the chip itself. With a free NFC reader app you can see every train ride and konbini purchase without queueing at a station machine.
Install the IC card balance checker app from nfcjp.com, open it and tap your card on the back of your phone. The list of recent transactions appears together with the current balance.
No login, no top up, no internet. The app reads the chip directly.
