FAQ
Frequently asked questions
My transit card is not detected.
Hold the card near the top of your iPhone and keep it still for a moment. A thick case or other cards nearby can interfere, so separate them and try again.
Which transit cards are supported?
The app currently supports the cards identified in the app, including Tmoney and Cashbee/EZL. Some cards may not be detected when their type or NFC data format differs.
The balance is different from what I expected.
The app shows the balance read from the physical card at scan time. Try again after a recent top-up or transaction has been written to the card. Contact the card issuer for balance settlement questions.
Where is my scan history stored?
Transit card information and scan history stay only on your iPhone and are not sent to the developer’s server. You can delete records for one card or all records in the app.
How do I change advertising privacy choices?
Review the advertising privacy options available in the app and the tracking permission in iPhone Settings. Available choices may vary by region and consent status.
