Public Transport Cards¶

Resources¶
MIFARE Classic¶
If your transit agency is using MIFARE Classic, then follow this awesome guide.
MIFARE DESFire¶
If your transit agency is using MIFARE DESFire, then use either your Flipper Zero or the MetroDroid app to see if your transit card has any unlocked applications/files that reveal information such as:
- Card name;
- Card number;
- Fare type;
- Product type;
- Machine code;
- Current balance;
- Last/recent transaction date[s]/time[s];
- Vehicle type;
- Weekly journeys;
- Transaction counter
If the card is fully-locked, then the only valuable piece of information would be the six hexadecimal Application IDs; these may be found by looking at the Flipper Zero .nfc file or by scanning your card via the NXP TagInfo by NXP app.
