fetch public key from card?

[Stefan Xenon]

Hi!
When using "gpg --card-edit" and "fetch" gnupg tries to download the
public key from a key server. Instead, is it possible to fetch the
public key from an OpenPGP Card v2.0 directly? If so, how to do this?
Otherwise do I need to keep a backup of my public key always together
with my OpenPGP Card?

Best regards
Stefan
