Anon 110210- I am not sure which materials are used. I do know that a company by the name of Pyramid Technologies is a well known provider for punch cards.
I just wanted to say that punch cards are often used to record an employee’s time at work. They are also referred to as time cards.
An employee punch card is issued when an employee starts a job. He or she is given a numerical card that the employee will be required to use when they enter the job site to start their work day and when they go home.
The timeclock will register the exact time of arrival and departure when the card is placed in middle slot of the time clock. While this time clock is a manual time clock, many businesses are now using electronic time clocks that calculate weekly totals along with payroll.
This is especially important if the business is larger because it could be time consuming to use a business punch card from a manual time clock in order to process payroll for over 100 people. In this case the electronic punch card clock is much better.
