Product information "OpenPGP Smart Card V3.4 + MiFare DESFire"

This special version of the OpenPGP card contains, in addition to the OpenPGP V3.4 chip, a MiFARE-DESFIRE EV1 4k compatible NFC / RFID chip. This card can also be used as NFC / RFID token with other applications.

The pictures are still showing version 2.1 of the OpenPGP card. 

The OpenPGP function can not be used via NFC / RFID. For this, a chip card reader for contact-related cards is necessary in any case.

The DESFire EV1 function can be used, for example, with the so-called RFID "basic reader", which has been disseminated in connection with the new German ID card.

Though the OpenPGP card specification V3.3.1 or later is available, there are no concrete plans yet about their implementation.

Hints / FAQ

After three wrong PIN entries the card will lock itself and must be unlocked using the admin PIN. After another three false attempts using the admin PIN the card will be permanently locked and only be unlocked with a card reset. This will reevocably destroy all data stoerd on the card - thus also all keys!

The current stable version of GnuPG (2.2.x and even some of the 2.1
versions) feature a factory reset command:
$gpg --card-edit
gpg> admin
gpg> factory-reset

CAUTION: All data will be lost!
