## Software

OpenCT implements drivers for several smart card readers. OpenSC can use OpenCT directly without the need for an additional middleware, and this combination is preferred by some authors and tested all the time, works perfectly.

The M.U.S.C.L.E. project offers the open source software PC/SC-Lite and links to many drivers in ifdhandler format, and also to some applications.

Some drivers in CT-API format are available for download at Gregor's CT-API-Page.
