The TachoSAFE RDU Multi Company Manager can't see more than 10 smart card readers.

Many customers have noticed that the Windows PC/SC subsystem is not able to handle more than 10 readers (or slots in case of multi-slot readers). Microsoft clearly states in Limitation of 10 smart card readers in Windows Server 2012 R2, Windows 8, and later:

 "Starting in Windows 8, the Windows platform supports a maximum of 10 smartcard readers. If more than 10 smartcard readers are available, APIs such as SCardListReaders return a maximum of 10. All other readers are ignored." So, sorry, but there’s no way to use more than 10 PC/SC readers (or slots) on a Windows 8 or Windows 10 system.

For more than 10 smart card readers on your computer choose our solution with a special build of Linux. If you still want to stick with Windows then you can use the Lisle Hyper Card Rack solution which is also supported by our Multi Company Manager application.
