Passy: Flipper Zero Passport Reader

June 8, 2026 · View on GitHub

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.

Features

  • 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)

Tested with the following countries

🇺🇸 🇨🇱 🇫🇷 🇬🇧 🇵🇭 🇷🇺 🇹🇼 🇺🇦 🇦🇿 🇨🇦 🇮🇹 🇪🇸 🇪🇪 🇨🇭 🇦🇺 🇭🇰 🇦🇹 🇳🇱 🇬🇪 🇰🇷 🇨🇳 🇸🇬 🇧🇩 🇧🇬 🇯🇵 🇬🇷 🇨🇷 🇹🇷 🇲🇽 🇷🇸 🇹🇭 🇫🇮

If it works for yours, submit a PR to add your country flag!

Usage

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.

Limitations

  • 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)

Development

Prerequisites

  • Flipper Zero device (updated firmware recommended)
  • ufbt for building
  • asn1c ASN.1 compiler (for protocol/data parsing)

Installation

Clone this repository:

git clone https://github.com/bettse/passy.git
cd passy

Build the ASN.1 code (optional, required for development):

asn1c -D ./lib/asn1 -no-gen-example -pdu=all eMRTD.asn1

Roadmap / To Do

  • Support PACE protocol
  • Add support for more countries' passports
  • Improve parsing of additional DGs
