There are two possible fixes to this issue:

  1. Attempt encoding again with new, unused UHF cards.  UHF contactless cards can come with intricate security features that can lock a user out after successive failed attempts to write information.
  2. Update the file ZBRUHF.dll to version  Make sure that no earlier version of ZBRUHF.dll resides in either the Win32 directory or in the project's bin directory.  Contact a member of the Card SDK group at Card_SDK_Questions@zebra.com to get a copy of this library.
