Enabling MIFARE DESFire for transparent OSDP readers

2024-05-08Last updated

OSDP readers in transparent mode require you to store the keys on your Synergis™ Cloud Link unit, or on secure access module (SAM) cards if you have the Synergis Cloud Link 312 model.

Before you begin

Configure the MIFARE DESFire keys on your Synergis Cloud Link unit.

What you should know

Card or PIN mode is not supported with OSDP readers configured in DESFire mode (transparent mode).

Procedure

  1. Log on to the Synergis Cloud Link unit.
  2. Click Configuration > Hardware , and then select an enrolled OSDP reader.
  3. Click Edit () for the selected reader's interface.
  4. From the Reader type list, select Transparent reader (MIFARE DESFire).
    Properties dialog box of an OSDP reader in the Synergis Appliance Portal with Transparent reader (MIFARE DESFire) selected as the Reader type.
  5. From the MIFARE DESFire key location list, select one of the following:

    Synergis key store
    The key for decrypting credentials is stored on the Synergis unit. This option does not require a SAM card.
    SAM (Software crypto)
    This is the faster of the SAM options, but requires the SessionDumpKey option to be enabled during the SAM configuration process. For more information, see the documentation that came with your SAM card configuration software.
    SAM (Hardware crypto)
    This option does not require SessionDumpKey to be enabled during the SAM configuration process.
    Note: The SAM options are only available if you have the Synergis Cloud Link 312 model.
  6. Click Save.
  7. If you selected the Synergis key store option, use the Synergis™ Appliance Portal to access the Synergis key store and enter the keys:
    1. Select an index.
    2. Click Create new version, and enter a 32-character hexadecimal key in the text field.
    3. Click Add.
    The MIFARE DESFire configuration file used for the indexed keys is compatible with both software-transparent and non-transparent readers.
    Limitation: There are two limitations with software-transparent readers:
    • Transparent readers currently cannot encode cards.
    • Cards with transparent mode enabled take about 100 ms longer to read.

After you finish

Configure MIFARE DESFire.
