Passy: A Flipper Zero Passport reader

Tested with the following countries:

🇺🇸 🇨🇱 🇫🇷 🇬🇧 🇵🇭 🇷🇺 🇹🇼

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

To use:

eMTRD are secured to prevent people from reading the data on a passport just by bumping into it. The data is secured using a key based on the passport number, date of birth, and date of expiry. A real passport machine reads these values from the MRZ (Machine Readable Zone, the ones with ">") using a camera. For the app, you have to enter the values manually. The app will then generate the key and read the data using a system called BAC(https://en.wikipedia.org/wiki/Basic_access_control).

Limitations

  • Does not parse some of the optional DG (under 'advanced' menu)

To do

  • Support other country passports

Generate asn:

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