The PIN is passed to the card and processed by the card.  Thus the card
decides on whether an operation needs a PIN.  Usually the PIN is
required only once and valid until the card is powered down
(e.g. unplugged).  The OpenPGP card may require a PIN for each signing
operaion - this behaviour can be controlled using the "forcesig" command
of gpg --card-edit.

To do the verification without any operation you can use "gpg
--card-edit" and then enter "verify".

If you want to see the commands send to the scd run
gpg --debug ipc --card-edit
