Supports Visual Face Migration

In order to improve the usability of customers, the criteria of the algorithm for extracting Visual Face templates from photos have been updated while improving the Visual Face performance. Accordingly, even with Visual Face credentials that had no problems with registration and used in BioStar 2 v2.8.6 - v2.8.17 and FaceStation F2 v1.x.x, the latest BioStar 2, v2.9.0 and above, and FaceStation F2 v2.x.x, BioStation 3 may not be available.

In Suprema, Visual Face Migration in BioStar 2.9.0 notifies which user's photo needs to be replaced so that customers who have been using Visual Face since FaceStation F2 v1.x.x do not experience inconvenience even after upgrading or adding new devices.

To understand Visual Face extraction improvements, please refer to the article below: Improved Image Extraction for Visual Face Credentials

  • The user must manually run this function.
  • Upgrading BioStar 2 to v2.9.0 or higher version does NOT automatically check the compatibility of Visual Face.
