APPENDIX C. APPLICATION FAMILY IDENTIFIER (AFI) CODING

AFI (Application Family Identifier) represents the

type of application targeted by the VCD and is

used to extract from all the LRI64 present only the

LRI64 meeting the required application criteria.

It is programmed by the LRI64 issuer (the pur-

chaser of the LRI64). Once locked, it can not be

modified.

The most significant nibble of AFI is used to code

one specific or all application families, as defined

in Table 21.

The least significant nibble of AFI is used to code

one specific or all application sub-families. Sub-

family codes different from 0 are proprietary.
