Pick a Card, Any Card: Fast and easy Windows logon using any NFC smart card

After finally reinstalling Windows on my main PC (the smart card components in the old install were trashed), I dusted off the old smart card reader and started looking into smart card-based logon options again.

After finding a way to force convince the installer for EIDAuthenticate, a program that lets you use smart cards to log on a Windows computer without the use of domains and Active Directory, to run on Windows 7 Professional (Microsoft DreamSpark only lets me obtain the Professional editions of Windows), I found a program called NFC Connector Light that lets you use any NFC-compatible smart card as a means of authentication.

NFC Connector Light links the unique identifier in an NFC-based smart card to create a virtual smart card on the local computer (no data is stored in the card itself), and that virtual card can be used like a real smart card within Windows. When paired with EIDAuthenticate, logging on is as simple as placing the smart card on the NFC reader and entering a PIN. This is especially useful when you set the Windows smart card policy to lock the computer when the card is removed (and it feels kind of cool to be able to lock your computer simply by taking your card off the reader).

Mini-Ramble: I’m such an icon artist!

After working so much with these battery chips, I thought I should spice up the Windows file icon for the .gg files that clutter my documents folder.

I’m not a person for glossy icons, but I’m also not a fan of the super-flat colour scheme that the Windows Metro UI uses. I prefer the good old style of Windows 9x-esque icons (hey, it’s what I grew up on! 🙂 ), albeit with a more… contemporary colour scheme. Keep it simple!

You can use Nirsoft’s FileTypesMan to add an icon in Windows. Personally, I configured it so that .gg files open up in Notepad++ for manual editing.

Update: How to install Windows x64 drivers for the Schlumberger Reflex USB smart card reader

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.

2. Open Device Manager, and select the “SLB ReflexUSB SmartCard Reader” in the list.

3. Follow the wizard and opt to install the drivers manually.

4. Enjoy your now-functional smart card reader.

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.
