Biometric time and attendance solutions exist to keep track of who is where and when they’re there.
In its most basic form, time and attendance tracking is a schedule, in which workers, volunteers, or students write down entry and exit times so that they can be logged. A slight step up from that rudimentary system, you will find punch cards, or shared digital spreadsheets. But all of these systems have a critical flaw: they can’t prove you are who you say you are. Truants can have a friend sign in for them or punch their card—a fraudulent practice termed buddy-punching—and effectively steal time from employers or falsely claim hours of work they otherwise spent elsewhere.
