Using Wyse C30LE Ver 6.0 Wyse WRF 4 Hotfix 1 Build 665 Win CE 6.0 RDP 6.0 connecting to Windows 2003 Terminal Server attempting to use a SCR3310 smart card reader, I have 90 Meter software installed. When using a ActiveIdentity CAC card the software see the reader and is aware when the card is removed. The package provides the installation files for SCM SCR3310 USB SmartCard Reader Driver version 4.65.0.0. If the driver is already installed on your system, updating (overwrite-installing) may fix various issues, add new functions, or just upgrade to the available version. Jul 19, 2018 This manual provides an overview of the hardware and software features of the SCR3310 V2 smart card reader. This manual describes in details interfaces and supported commands available for developers using SCR3310 V2 in their applications. 2.2: Target audience This document describes the technical implementation of SCR3310 V2. Identiv SCR3310 Smart Card Reader works on Windows, Mac, iOS, Android, and Linux. However, depending on the level of your operating systems, you many need to install a driver. To use your CAC with your computer, you’ll still need to download the appropriate drivers (in some cases) as well as the necessary DOD certificates.

This topic for the IT professional and smart card developers describes how the Smart Cards for Windows service (formerly called Smart Card Resource Manager) manages readers and application interactions.

The Smart Cards for Windows service provides the basic infrastructure for all other smart card components as it manages smart card readers and application interactions on the computer. It is fully compliant with the specifications set by the PC/SC Workgroup. For information about these specifications, see the PC/SC Workgroup Specifications website.

The Smart Cards for Windows service runs in the context of a local service, and it is implemented as a shared service of the services host (svchost) process. The Smart Cards for Windows service, Scardsvr, has the following service description:

Note For winscard.dll to be invoked as the proper class installer, the INF file for a smart card reader must specify the following for Class and ClassGUID:
Class=SmartCardReader
ClassGuid={50DD5230-BA8A-11D1-BF5D-0000F805F530}

By default, the service is configured for manual mode. Creators of smart card reader drivers must configure their INFs so that they start the service automatically and winscard.dll files call a predefined entry point to start the service during installation. The entry point is defined as part of the SmartCardReader class, and it is not called directly. If a device advertises itself as part of this class, the entry point is automatically invoked to start the service when the device is inserted. Using this method ensures that the service is enabled when it is needed, but it is also disabled for users who do not use smart cards.

When the service is started, it performs several functions:

It registers itself for service notifications.
It registers itself for Plug and Play (PnP) notifications related to device removal and additions.
It initializes its data cache and a global event that signals that the service has started.

Note For smart card implementations, consider sending all communications in Windows operating systems with smart card readers through the Smart Cards for Windows service. This provides an interface to track, select, and communicate with all drivers that declare themselves members of the smart card reader device group.

The Smart Cards for Windows service categorizes each smart card reader slot as a unique reader, and each slot is also managed separately, regardless of the device's physical characteristics. The Smart Cards for Windows service handles the following high-level actions:
