New Features

  • System
    • Support for Mifare/Desfire card when used with SW6000
      • When using SW6000, the MXC system can now be configured to provide:
        • The User ID/Login code data from ACOS3 NFC cards programmed from SW6000 (current feature) or
        • The Unique ID on a Mifare/Desfire NFC card or an ACOS3 NFC card (new feature)
      • Benefits
        • Using the Unique ID enables usage of cards where no (meeting) data has been written to the card
        • This makes it possible to use cards that are provided to users for other purposes to login to SW6000, so the user needs to hold one less card
