Update (December 11, 2017): For those on Windows 10, click HERE for the SCR300 driver package – digitally signed to ensure compatibility. Extract the files, right-click the appropriate x86/x64 .INF file and select “Install”. Proceed with the installation as shown below.
A viewer requested help on installing the drivers for the Schlumberger Reflex USB smart card reader, so I’ve created a step-by-step instruction guide on doing so.
1. Plug in the smart card reader into an available USB port. Windows should attempt to install a driver but won’t succeed.
Windows detecting reader…
Of course, no drivers found yet.
2. Open Device Manager, and select the “SLB ReflexUSB SmartCard Reader” in the list.
Enter “devmgmt.msc” in the Run window to open Device Manager.
Select the “SLB ReflexUSB SmartCard Reader” from the list.
Click “Update Driver…” to begin the driver installation process.
3. Follow the wizard and opt to install the drivers manually.
Choose “Browse my computer for driver software” as Windows will not be able to to auto-select the driver for you.
Select “Let me pick from a list of device drivers on my computer”. This will allow us to force a driver install for the smart card reader.
When presented with a list of devices, scroll down to “Smart card readers” and click Next.
Scroll down to “SCM Microsystems” under the Manufacturer list, and select the “SCM Microsystems SCR300 USB Smart Card Reader”. Windows should say that the drivers are digitally signed.
Windows will alert you that the device driver may not be compatible; click Yes to continue.
Once you see “Windows has successfully updated your driver software” your smart card reader should work properly now.
Windows now recognizes the smart card reader.
4. Enjoy your now-functional smart card reader.
The reader is recognized in Windows, and in PC SC Diagnostic, a third-party application.

A while back a friend of mine gave me an old smart card reader that was of no use to him; he had no need to use smart cards at home and the reader he gave me, a Schlumberger Reflex USB reader, had no support in 64-bit Windows 7, or so it seemed.
I cracked open the reader (didn’t take any effort, there are no screws nor snap-clips holding the case together) and found the internal part number: an SCM Microsystems SCR301 reader. Forcing Windows to use the SCM Microsystems SCR300 driver was successful in getting the reader to show up in Windows, meaning that I had a free, usable smart card reader to tinker around with. Awesome.
Update on June 20, 2013: Added a screenshot of the reader in Device Manager.
