Security is an important factor when using Bit-Cards. Therefore we would like to elaborate on some security characteristics protecting the cards from counter fitting and inappropriate use.

    When you receive a Bit-Card, you should check it by using the verification link printed on the front of the card. This link will provide essential information about the card and its status.

Hologram security characteristics

In order to determine whether the private card key has already been accessed, the key is protected by a special security hologram. If this hologram is removed it will self-destruct. Never accept a Bit-Card if the security hologram is damaged or has been removed!

Security cut

    We continuously work to further improve the security features of our Bit-Cards. After extensive testing of different enhancements, we decided to introduce the following new security feature for all Bit-Cards produced as of 2013-07-23:

    The Security Cut is carved into the hologram. Four overlapping Bitcoin-Symbols form a pattern and segment the hologram into more than thirty parts of different size making any attempt at opening it or tampering with it even more obvious.

    Black core

In addition to the characteristics outlined here, the hologram features numerous other characteristics which render it impossible to be duplicated.

Sandwich configuration

    Bit-Cards are not only thicker than required by the ISO/IEC-Standard 7813 ID-1, they also feature a black core to adequately protect the private key.
