CardBal reads supported transit IC cards over NFC and keeps your card history organized on your device. View saved cards, balances, decoded trips, and route points, then export or import a CardBal backup that also works with CardBal on iOS.
Supported data includes Japanese Transit IC, China T-Union, and Korean transit-card records where available. The Android app uses a native Material 3 interface with stacked card browsing, map views for decoded trip locations, and settings for cross-platform backup files.
Card data is stored locally on your device. Imports and exports happen only when you choose a backup file.
