Abstract: A computer-based system for management of field staff may include a central computer server and a plurality of mobile devices for communication with individual staff. The central computer server may be configured to generate individual notifications to at least a selected portion of the individual staff, and communicate these notifications to respective mobile devices assigned to this selected portion of individual staff. Upon receipt of at least some confirmations, the central server may generate and communicate individual barcodes to all responders. These barcodes may be used to register an individual staff upon arrival and record working hours while at the field event.
