You most likely do *not* want to use smartcard *contact* readers as a 
physical access control system (PACS), except in special, very 
low-volume areas.  They tend to be a bit slow to interact with.

Better is to use a dual interface card with a standard RF proximity 
interface (non-PKI, I might add) for PACS, and PKI keys loaded on a 
contact chip for logical access control systems (LACS).

Dual cards are also far, far easier to integrate into an existing PACS.

Note that the US Fed PIV smartcard is a dual interface card, with the 
wireless interface intended for PACS.
