The OpenPGP card
The OpenPGP Card is a specification of an ISO 7816-4,-8 compatible smartcard and also an actually available implementation of this specification as a standard sized card.
Note: g10code is not the vendor of the card. We implemented the support for the card in GnuPG and helped with the specification. The card sold by kernel concepts (now known as FLOSS-Shop) are based on a hardware and the Card OS provided by ZeitControl; the software on this card is not available as free software due to NDAs required for certain parts.
