How to make GPG release the token?

[Nguyễn Hồng Quân]

Thanks David,

I'm starting to develop  OpenSC to make it support fully the 
CryptoStick (which uses OpenPGP card). So I cannot uninstall OpenSC.
Because the OpenSC does not support OpenPGP card fully, I sometimes use 
GPG to test the card.

So there is no way to leave these two together?
