Passy is a tool for reading electronic passports (ePassports/eMRTDs) using the Flipper Zero device. It extracts and decodes data securely stored in modern passports, designed for hobbyists, researchers, and security professionals.
- Reads and decodes ePassport data from a wide range of countries
- Utilizes MRZ (Machine Readable Zone) information for secure access
- Extensible for new country support—contribute your flag!
- Advanced menu for debugging and exploring additional data groups (DGs)

If it works for yours, submit a PR to add your country flag!
eMRTDs are secured to prevent unauthorized reading. The key for accessing the data is derived from:
- Passport number
- Date of birth
- Date of expiry
Use the Flipper Zero to scan your passport’s NFC chip and enter the required information.
- Advanced menu is hidden unless Debug mode is enabled
- Some data groups (DGs) are not fully parsed under "advanced" menu
- Country coverage is limited (see above)
- Flipper Zero device (updated firmware recommended)
- ufbt for building
- asn1c ASN.1 compiler (for protocol/data parsing)
