Known Issues:

  1. When the application (including Rohos) opens a COM port then other
    apps can’t open this COM port again. Rohos opens a COM port only for
    login, or Tag setup operations.
  2. If you have other apps that should work with a reader they could
    conflict with Rohos.  If so, do not use “USB Key removal” settings.
  3. If you have an applications that keep this reader opened (and COM
    port) it is possible that COM port will be locked thus for example the
    following use case will not be possible:
    – user turn on a PC and login with a TAG,
    – a 3rd party Application runs on the desktop and  working with Easident reader all of the time (COM port is locked).
    – user lock the desktop and try to unlock it with a TAG by using Rohos Logon Key
    – Rohos will not be able to connect COM port – and this user will not login by a TAG.
  4. Rohos reads RFID tags by KCY and PcProx RFID readers by using USB connection mode, so you may disable keyboard mode.
  5. PIN code functionality and Active Directory authentication are supported as well.
