I use mine every time i have a large project, I have a small bench in my enclosed trailer and the machine is set up on it. Every time they take a lunch break or leave the job they have to punch out and punch back in. I only pay for the hours on the card so it encourages them to stay on the job longer. The headache of worrying about watching over your employees is gone, and its so much easier to do the books because you have a paper trail. The only problem is when people dont punch out. I had to start taking off 2 hours for lunch every time was handed to me without a lunch punch out.
Im not sure what brand I use, i know its green though.... abcoprints??
