I wrote this page, when I added the support of pinpad input to scdaemon.

Since Werner has SCM SPR 532, it was tested and listed.  Please note
that the list is not for recommendation (as of today); Vasco DigiPASS
920 (which I have) worked, but it only supports key length <= 1024-bit
of RSA.  Gnuk Token is listed, but it has no hardware pinpad, in fact.
Some other readers were listed because they requires special handling to
work around issues of their firmware.

I think that: if you need a tested reader, go for the 532.  If you have
time and energy, go for the 332 and please let us know if it works or
not.  I guess that it is likely work well with PC/SC and we need a bit
of change for the internal CCID driver of GnuPG.  If it will work, I'll
put it on the list.  That will be a great contribution to GnuPG
community.
