The second PIN is only required due to peculiarities of the ISO-7816 standard gpg tries to keep this PIN in sync with the first PIN. gpg makes sure that the two numbers are synchronized.
The first and second PIN are for the standard PIN. They are reset whenever a correct AdminPIN is entered. They are decremented whenever a wrong PIN is entered. This field saves how many tries still are left to enter the right PIN. The values are put on the card right after personalisation - this is the moment after the chip has been glued on the card. When set to "non forced", gpg may cache the PIN as long as the card has not been removed from the reader. When set to "forced", gpg requests the entry of a PIN for each signature operation. This is a field reserved for arbitrary data.
See the source (app-openpgp.c) for some special features of the login-name field. gpg does not enforce any match of this name with a name used in the key. This field may be used to store the account name of the card holder. It may contain an URL to be used to retrieve the public key. Used by the fetch command of gpg -edit-card.
