To use application read key versions with your MIFARE SAM AV2 cards, configure the cards with up to three keys using a SAM card configuration tool, then enable key versioning in Synergis™ Appliance Portal.

Before you begin

  • Configure your SAM cards with up to three keys using a SAM production tool like ISLOG SAM Manager. For more information on SAM Manager, see Configuring MIFARE SAM AV2 cards.
  • Install the SAM cards into a Synergis™ Cloud Link equipped with an optional expansion module. For more information, see the SY-CLOUDLINK-312 Quick Start Guide.

What you should know

By default, Security Center does not support SAM cards with application read key versions other than 0; enabling key versioning allows the use of pre-encoded cards that have key versions other than 0. The feature works with OSDP and SSCP protocols, and offers key management flexibility to administrators who want to periodically increment their key version.


  1. Log on to the Synergis™ unit.
  2. Click Configuration > MIFARE DESFire.
  3. In the MIFARE DESFire versioning section, select the Use key version check box.
    If the check box is cleared, the system uses the last key version you created.
    If you select the check box, then add versions 1, 2, and then 3 for the indexed 01 key, when you clear the check box, only version 3 is listed in the Synergis™ key store for that key. If you create version 4, and then select the check box again, versions 2, 3, and 4 are listed.
  4. Click Save, and then restart the unit.
