Application family identifier (AFI)

The AFI (application family identifier) represents the type of application targeted by the VCD

and is used to identify, among all the LRI2Ks present, only the LRI2Ks that meet the

required application criteria.

Figure 36.

LRI2K decision tree for AFI

The AFI is programmed by the LRI2K issuer (or purchaser) in the AFI register. Once

programmed and Locked, it can no longer be modified.

The most significant nibble of the AFI is used to code one specific or all application families.

The least significant nibble of the AFI is used to code one specific or all application

subfamilies. subfamily codes different from 0 are proprietary.

(See ISO 15693-3 documentation)
