He does NOT want to use this device, his question was if it is possible to
use a smartcard (the OpenPGP card but as far
as I know almost every smartcard has a TRNG that can be read from with the
same command) as entropy source.
This is, in fact, possible and there is a small tool that does exactly that
available at
