A time clock, sometimes known as a clock card machine or punch clock or time recorder, is a recording clock used at places of business to record the hours worked by employees.
In regard to mechanical time clocks, this was accomplished by inserting a heavy paper card, called a time card, into a slot on the time clock. When the time card hit a contact at the rear of the slot, the machine would print day and time information (a timestamp) on the card. One or more time cards could serve as a timesheet or provide the data to fill one. This allowed a timekeeper to have an official record of the hours an employee worked to calculate the payment owed to an employee.
Time Recorders find usage to Record, IN & OUT Timing, Daily Late Coming, Early Going Report, and Leave Record, O. T. Calculation of the employees in large scale, small scale industries, Offices, Hotels, Hospitals, Banks, Department Stores, etc.
