Yes. When tradespeople leave your project you can reuse the same beacon on a new tradesperson that come to the site. In Eyrus a beacon can only be assigned to one person one a given day so you cannot take if from Susan on Wednesday and then give it to Sally on Wednesday. Based upon how you set the dates either all of Wednesday will go to Susan or all Sally. Because of this when you take a beacon back from an tradesperson we recommend to put the beacon back in the bag for future registrations.
