Aligo (www.aligo.com) introduced four new products at the AHR Expo including the WorkCenter, which provides project managers, supervisors, and business owners easy access to job status, employee status, and employee locations while working in the field. WorkSite is a timecard replacement solution typically used by large construction companies. CardSwipe allows employees to start and stop their time using a magnetic identity card. This card is swiped through a card reader attached to a WorkTrack-enabled phone carried by a supervisor.
