CEVAP:

The most common way to track labor costs is keeping labor time cards for many years now. The firm assigns a card to each employee. Timecard can be a physical piece of paper. In such a case as the employee enters or leaves the firm, he/she inserts the card in the clock and that clock prints the exact time for arriving and leaving. In addition, the timecard can be a virtual record updated as the employee checks in and out and enters the job number in a computerized information system.
