CSSI Secure PIN Entry

CSSI Supports Secure PIN Entry (SPE).


The following readers have been tested:

  • Cherry Keyboard G83-6644
  • HID Omnikey 362 & 3821 USB
  • Identiv/SCM SPR532


Other compatible SPE readers from other manufacturers are known to work.



Although CSSI supports alphanumeric PINS in general, SPE only supports digits. Please make
sure the PINs used for the card can be entered by using SPE.


Enabling SPE on Microsoft Windows:

Edit the registry setting at
[HKEY_LOCAL_MACHINE\SOFTWARE\charismathics\smart security interface]
To activate SPE, use: "USE_PINPAD"=hex:01
To deactivate SPE, use: "USE_PINPAD"=hex:00
