Using a smart card

You can use NICE DCV to use one or more smart cards that's connected to your client computer. You can do this using the standard Personal Computer/Smart Card (PC/SC) interface, in a NICE DCV session. For each session, only one connected client can connect a smart card at a time. This is especially important in environments where multiple clients connect to the same session.

Smart card access is supported only with the Windows, Linux, and macOS clients. It's not supported with the web browser client.

Only one client can connect a smart card at a time. While your smart card is connected, no other clients who are connected to the session can connect a smart card.

After you're done using the smart card in the NICE DCV session, release it. After it's released, other clients who are connected to the session can connect a smart card. The smart card is automatically released when you disconnect from the session.

You must be authorized to use this feature. If you are not authorized, the functionality is not available in the client. For more information, see Configuring NICE DCV Authorization in the NICE DCV Administrator Guide.

Smart card data caching (optional)

To have the NICE DCV server cache smart card data, you will need to enable the smart card caching feature. By default, smart card caching is disabled. With smart card caching enabled, the server caches the results of recent calls to the client's smart card. This helps to reduce the amount of traffic that is transferred between the client and the server and improves performance.

You cannot enable smart card caching if it's disabled on the server. For more information, see Configuring Smart Card Caching in the NICE DCV Administrator Guide

Enabling smart card caching on Windows servers

1. Launch the client and connect to the NICE DCV session.

2. Open a terminal window.

3. Run one of the following commands:

   • To enable smart card caching for the current terminal window:

     C:\> set DCV_PCSC_ENABLE_CACHE=1

   • To enable smart card caching permanently for all applications on the server:

     C:\> setx DCV_PCSC_ENABLE_CACHE 1

Enabling smart card caching on Linux servers

1. Launch the client and connect to the NICE DCV session.

   Note

   Make sure to run the following command in the same terminal that you intend to launch the application.

2. Open a terminal window where you ran the applicaiton with dcvscrun.

3. Export the DCV_PCSC_ENABLE_CACHE with the value 1.

   For example, you might run the command:

   $  DCV_PCSC_ENABLE_CACHE=1 dcvscrun APPLICATION

   or

   $  DCV_PCSC_ENABLE_CACHE=1
   $  dcvscrun APPLICATION
