It shows the status of the card (as same as the output of gpg --card-status).

Then, GnuPG enters its own command interaction mode. The prompt is gpg/card>.

First, enabling admin command, I put name of mine. Note that I input admin PIN of factory setting (12345678) here.

gpg/card> admin
Admin commands are allowed

gpg/card> name
Cardholder's surname: Niibe
Cardholder's given name: Yutaka
gpg: 3 Admin PIN attempts remaining before card is permanently locked

Please enter the Admin PIN
Enter Admin PIN: 12345678

Secondly, I put some other informations, such as language, sex, login, and URL. URL specifies the place where I put my public keys.

gpg/card> lang
Language preferences: ja

gpg/card> sex
Sex ((M)ale, (F)emale or space): m

gpg/card> url
URL to retrieve public key:

gpg/card> login
Login data (account name): gniibe

Since I don’t force PIN input everytime, toggle it to non-force-pin-for-signature.

gpg/card> forcesig

Then, I quit.

gpg/card> quit

That’s all in this step.
