- Reading NFC passport chips in Linux using pypassport.
- Passport NFC chip requires a password derived from the MRZ (Machine Readable Zone).
- Cancelled passports may have MRZ partially destroyed but NFC chip remains functional.
- MRZ password components: Passport Number, Date of Birth, Expiry Date, each with checksums.
- Python code provided to generate MRZ and calculate checksums.
- Brute-forcing passport MRZ is theoretically possible but impractical due to large combinations.
- Passport data includes biometrics, personal details, and metadata stored in Data Groups.
- Saving passport photo from NFC chip demonstrated with Python.
- Various tools attempted; pypassport works best for Linux.
- Security relies on standard Public Key Cryptography; no brute-force lockout mechanism.
