Construction manpower tracking traditionally consists of pen and paper tracking to ensure the right workers are on-site. Modern technological advances have tried to improve the process, but some of these methods haven’t had as much success since they’re easy to trick. One successful technology is facial biometrics to document attendance and track headcount, which provides you with a much more accurate picture of who is on the jobsite. The SmartBarrel device is the perfect solution for efficient construction manpower tracking.
