Adding a card configuration

The following sections describe how to determine a card configuration for your locking system and how to configure it in your AXM Classic .

Available RFID identification media

The description refers to “cards”. However, the procedure is similar for all supported RFID identification media; for example:



Card analysis by SimonsVoss

Analysing your cards and finding the right card configuration for trouble-free operation can be challenging, especially when it comes to cards already in use.

That's why SimonsVoss offers you to help.

  1. If you decide to have your card checked by SimonsVoss: Feel free to contact one of our sales representatives in your region.
  2. If you want to determine the card configuration yourself: Read through the following sections carefully.

Basis: MIFARE DESFire and MIFARE Classic

MIFARE DESFire and MIFARE Classic encryption technologies are the most important for RFID identification media:

MIFARE Classic


  • Easy protection
  • Inexpensive identification media
  • Limited performance
  • Memory as numbers/letter sequence

  • Effective protection
  • High-performance identification media
  • Memory as a file system
  • More flexible handling

MIFARE Classic encryption is now considered non-secure. SimonsVoss therefore recommends using MIFARE DESFire only.

MIFARE Classic


  • Data stored in sectors
  • Addressing with sectors in sector list
  • Sector protection using the last block in sector
  • MIFARE Classic encryption hacked and now insecure
  • Data saved in files
  • Addressing with application ID
  • File backed up by file read key
  • Locking system data must be stored in an application file. Read access is required to the file.
  • Encryption with AES (128 bit)

Determine the values to be entered in advance

You need to determine the values before entering them. An NFC-compatible smartphone is ideal for reading your cards. The examples show Android with NXP’s TagInfo app ( The required report is the “full report”.

Make a note of the values determined. You proceed with this in a different way, depending on the situation:


You can then enter the values for the card configuration.

Entering the card configuration

  1. Locking system - Card configuration tab open (see Create locking system or Enable cards or transponders)
  1. Select your card type from the Card type drop-down menu.
  2. Select the configuration you require from the Configuration drop-down menu.
  3. Enter the remaining previously determined parameters in the section on the right.
  4. Click on the Finish button.
  1. The card configuration is set.
