9F2F

ICC PIN Encipherment Public Key Remainder is the overflow field for 9F2D, playing exactly the same structural role that 9F48 plays for the general ICC certificate (9F46) and that 92 plays for the Issuer Public Key Certificate (90): whatever part of the PIN-encipherment key's modulus doesn't fit inside its certificate spills into this separate field, to be concatenated back on by the terminal before the key is complete and usable. It's the third instance of the exact same pattern in this dictionary - modulus-in-certificate plus optional remainder - which is worth recognising as a pattern rather than three unrelated fields to memorise separately: any card whose keys happen to be short enough needs none of the three remainder fields (92, 9F48, 9F2F) at all, and their absence is normal, not an error condition. A terminal implementation that handles the general PK Remainder (9F48) correctly but mishandles 9F2F specifically has almost certainly special-cased one code path instead of sharing the same concatenation logic across all three certificate types.
