In my place of work, there's no time cards. Instead, personnel who show up each day are noted in a handwritten time-record which is later submitted to the man who pays. This paying boss is never at our workplace; he has an office in a relatively distant location. So the onsite guy who writes down the daily arrivals is providing the only documentation on which the paychecks are later based.
This guy happens to be me. So, though I come in just about every day, I can arrive late, leave early, and take the occasional day off, and I mark myself as having been at work and receive full pay.
