Correctly scope travel documents, MRZ, ePassport/eMRTD and NFC.
eMRTD TECHNICAL STACK
ICAO Doc 9303: from MRZ to trust chain
Separates data structure, security mechanisms and PKI. A capability is marked supported only when CheckID evidence confirms it.
02
BAC / PACE
Access-control mechanisms establish chip access before protected messaging.
03
Secure Messaging
Protected communication with the IC after access is established.
04
LDS & Data Groups
Part 10 defines the Logical Data Structure used to store biometric and document data.
05
SOD / Passive Authentication
SOD signature and Data Group hashes support integrity and issuer-authenticity checks.
06
AA / Chip Authentication
Clone-resistance mechanisms where supported by the document profile.
07
PKI
Part 12 covers the MRTD PKI trust chain, including Document Signer and CSCA roles.
08
