Get a Prox license for
HID Prox, Indala, or Keri cards

To read HID Prox, Indala, or Keri project cards, you need readers with a Prox license.

Which readers are affected?

  • Readers with 125 kHz support purchased as of 1 June 2020.
    Readers purchased before that date don't need a Prox license, even if their firmware is updated.

  • Readers with an HID iCLASS SE Processor have a Prox license enabled automatically.
    This means you don't need to purchase a license in this case.1

On ACCESS200 with firmware 1100 below v2.05, the Prox license disables the Wiegand interface.

This was due to contractual requirements on the part of HID. To fix this issue, update to firmware 1100 v2.05 or above.

How does licensing work?

  • The license covers HID Prox, Indala, and Keri project cards. It's not possible to purchase a license for just one of these card types.
  • You need to purchase a license for each reader.
  • The license is permanent and doesn't need to be renewed.
  • You cannot disable a license on a reader or transfer it to a different one.

How to order a Prox license?

You can either order readers with preinstalled licenses or use BALTECH LicenseCards to deploy the licenses yourself.

How to check if my reader has a Prox license?

You can check a reader's license using BALTECH ID-engine Explorer.

  1. Connect the reader to your computer.

    I have an Ethernet reader.

    To work with BALTECH tools, an Ethernet reader must be unconfigured, or required permissions must be granted in PKI Authentication and Encryption settings.

  2. Open BALTECH ID-engine Explorer.

    If you haven't installed it yet, you can download it here as part of BALTECH ToolSuite.

  3. In the bottom right, click Show Full Reader Info.

Which error codes indicate a missing Prox license?

If you develop your own host application, the error code HID.ErrLicense indicates a missing Prox license. It is produced by the following low-level commands:

Besides, the error code VHL.ErrNoTag, produced by the VHL.Select command, may among other things indicate a missing Prox license, too.

  1. For readers purchased between 1 June 2020 and 1 February 2025, a discounted Prox license SE had to be purchased. This license is now assigned automatically free of charge when an HID iCLASS SE Processor is inserted. ↩
