An NFC-capable iPhone running iOS 16 or later and a supported physical card. CardBal uses the iPhone’s NFC reader; you don’t need an extra accessory.
CardBal is designed for supported physical cards. Apple Wallet transit cards and cards inside another phone are not supported by this scanning flow.
CardBal reads card information. To add credit or pay for a journey, use the card issuer’s official services.
Each card family stores different information and a limited number of records. CardBal displays what it can read and decode; some stations or transactions may be unavailable.
Saved cards are stored on your device. iCloud can sync backups. Optional Korean-card contributions and station reports share the data described in their app disclosures; the app also uses Firebase Analytics. See the privacy policy for details.
Yes. Open a saved card or trip in CardBal to report a missing station or request a station-code correction. You can add a station name, optional details, and a map pin.
