card encryption. The reading keys of the lost project already uploaded into the 2N device will be

valid for newly encrypted cards too.

Card Mode

Select a card encryption mode:

Card may be used for other applications later on (best compatibility) – the cards will

be used primarily by the 2N systems. The card data will be encrypted, but the UIDs will be

readable by third party applications. The cards can be reformatted to the original state.

Card will be used only for access control with 2N devices (best privacy) – the cards will

be used exclusively in the 2N systems. The card parameters will be reset permanently. The

Random ID function is activated on the card upon encryption.

Card is already used for other applications (advanced settings) – third party

applications are loaded to the cards. In the next step, set the selected parameters of the

MIFARE DESFire cards whose access data are to be encrypted by 2N

PICard in the project.

Now complete the following:

Application ID (AID) – 2N

PICard code on the card. AID is preset to 53324E.

PICC master key type – PICC master key type for the cards to be encrypted by 2N

PICard.

PICC master key – PICC master key value for the cards to be encrypted by 2N

PICard.

Enable randomization of readable card ID – make sure that the card UID changes

randomly upon every reading. Thus, an unauthorized person cannot misuse the

card for user identification.

Encrypt cards in factory default state (change default PICC master key) – upload

the set PICC master key on other empty cards while encryption in the project. If this

option is unselected, 2N

PICard refuses to encrypt an empty card.

Warning

The main encryption key cannot be displayed or changed later.

Tip

It is important to keep both the project file and the main encryption key (MEK) to

enhance security. The ideal solution is to store the main encryption key (MEK) in a

safe offline space, e.g. a vault, safe box, etc.

Caution

The selection of the Card is already used for other applications mode is

irreversible.
