Abstract: An application system comprises a client computing device, a temporary worker computing device, an online system connecting the computing devices, and a mobile recruitment vehicle. The vehicle is configured to facilitate conducting mass face-to-face recruiting of temporary workers, making the temporary workers readily available to clients for on-demand booking. The vehicle includes applicant and screener workstations. The applicant workstation is configured to receive applicant data. The screener workstation is configured to retrieve background check information related to the temporary worker, and to provide authentication information configured to allow the client computing device to access the online system, based on the results of screening, the background check information, and the applicant data.
