RDMAC was a software application designed by NHDS in the early days of public data networks such as PakNet, MOBITEX, etc. It was designed as a job assignment and dispatch package that allowed small companies to manage their remote workforce simply and cost-effectively. Remote workers were equipped with a two-way data display device such as the InfoTAC 2-way pager or a palm-top PC and received work assignments over the chosen data network. They could then accept or reject jobs and update the status of each job as it progressed, allowing the office to manage resources more effectively. Motorola in Canada were responsible for rolling out the DataTac mobile data network around the world and engaged NHDS to convert the RDMAC package to run on their new system as one of the first applications to run on that network.
