CryptoTokenKit - PIN Caching on Smart Cards

Curious if anyone has any insight into the caching behavior or Smart Card PINs, and if there are options available to set to always prompt for PIN.

Example of the current challenge is that users can authenticate to an application using their smart card and entering their PIN, however it appears the PIN is cached until the user logs out of their laptop or restarts.

Any insight into modifying this behavior or suggested solutions is greatly appreciated.

Thank you. CD
