The Membertracker application provides a contactless attendance tracking technology for individuals attending in-person sessions. The organizations that benefit from our application range from healthcare, manufacturing, commercial employers and others. The system solves the problem of end-users not being able to carry identification cards either because of the physical environment or because of health reasons but need to be checked in to a office or commercial building. A good example would be where behavioral health patients who attend programs offered by healthcare service organizations don't need to carry an identification card or badge when checking in to a daily program.
