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.
