Card data read key - System description SVCN

Depending on the card data to be read, it may be necessary to store the card data read key (DESFire: Reading key of the application/file or Classic: Reading key of the sector). The read key is part of the card configuration and is saved together with it in the project file (*.ikp) and in the locking devices.

The read key is used by the locking devices to read only the relevant part of the card's memory space.

The card manufacturer or other users of the card provide the card's reading key, for example as a template file (*.ikt) or directly in plain text. For information, see the step-by-step manual.

Change/Loss

• Can be changed in SI tool
• All locking devices and cards must be reprogrammed
