A time card is a tool for monitoring and recording the number of work hours employees spend in the office on a day-to-day basis. It is used by an employer for determining the payroll and keeping track of tardiness and absences. It records the time in, time out, and the duration of work. Depending on the time card system, it can contain a detailed breakdown of the tasks accomplished throughout the project. The information on a time card can also be used for project costing, client billing, estimation and projection, and tracking and management.
