Will I be charged if I enter and leave a station without taking a train?
When you tap your IC card at a ticket gate, it records your entry. When you tap out after a journey, the fare is normally deducted from your balance. Entering and leaving the same station does not automatically make it free. Some stations charge an admission fee even if you did not take a train; others will not let you tap out at the same station.
If you entered by mistake and have not taken a train, go to the staffed gate or ticket counter at that station before tapping out. Show the card or phone you used to enter, explain what happened, and ask the staff to cancel your entry.
You can say 「キャンセルお願いします」 (Kyanseru onegaishimasu) — “Please cancel it.” To make the situation clearer, say:
「間違えて入りました。入場のキャンセルをお願いします。」
Machigaete hairimashita. Nyūjō no kyanseru o onegaishimasu.
“I entered by mistake. Please cancel my station entry.”
Staff can check your entry record and advise whether it can be cancelled without a charge. Rules depend on the railway and the circumstances; an admission fee may still apply. If you have already taken a train, tell the staff where you travelled, as the applicable fare is still payable.

Why are some trips missing after I scanned my card?
Japanese IC cards only store the 20 most recent trips (3 for e-money). Once these limits are reached, each new transaction overwrites the oldest record.
Scanning your card with Suikakeibo saves the available history on your phone. However, the app can only read records that are still on the card at the time of scanning. It cannot recover records that have already been overwritten.
This means that if you make more than 20 trips between scans, some trips will be missing from your history. For example, if you make 25 trips without scanning, the 5 oldest trips will no longer be available when you next scan your card.
To avoid gaps in your history, scan your card regularly, before you reach these limits. Records already saved in Suikakeibo stay on your phone even after they are overwritten on the card.
Why do I need to scan my card again and again to update the data?
Your card only holds information about the 20 most recent trips. By scanning it with Suikakeibo, you can save the data to your phone and keep a full history. For privacy reasons, the app cannot access the data without scanning the card, so you will need to read your IC card from time to time to get the most recent data.
Why do some of my trips not show up when I am using my commuter pass?
One limitation of most Japanese IC cards is that when using a commuter pass, no public records will be written for the stations covered by the pass. Thus, Suikakeibo can only read your trips and shopping expenses not covered by a commuter pass.
How can I bring my data to my new Android phone?
Suikakeibo uses Android Auto Backup, so your data will be automatically restored when logging in to your new phone with the same Google Account.
Since 3.8.0: If Auto Backup does not work properly, you can also create and restore a backup in `Settings`.
How can I track company expenses?
Suikakeibo helps you to get reimbursed for your company expenses without the hassle.
- Scan your card with Suikakeibo every other day.
- After scanning, mark company expenses with just two taps.
- When it's time for the report, export all the company expenses for the month.
- Using 'share after export', you can send the report right from your phone.
How do I install a widget on the home screen?
- Long tap an empty space on your home screen
- Select "Widgets"
- Find the "Suikakeibo" widget
- Long tap and hold to drag it onto your home screen
- You can now tap the pencil button to set up your widget
- choose which card you want to see
- choose the design (full color or card)
- show or hide the card name
