The GateKeeper Halberd token and the GateKeeper USB receiver should ALWAYS be in direct line-of-sight to ensure the best performance and accuracy in locking/unlocking the workstations. We recommend wearing the GateKeeper Halberd around your neck on a lanyard or carrying it around your waist on a carabiner. The closer the key is to the receiver, the better performance.
We highly recommend using a USB extension cable to help create your most optimal environment. Please refer to our data sheet on how best to go about this here.
