That reminds me.

I worked for a company where we punched in using an iButton (it's a pretty neat 1-wire thing that fits on a key chain).

The punch clock system was logged and then at the end of the month, they printed out a single A4 sheet for every employee for us to make corrections and sign. Of course, someone had the unenviable job of going over all those and applying the corrections.

We also had to write down hours spent on different projects in a completely different system that wasn't at all integrated with the punch clock system.

At some point in the last couple of years that I worked there, they switched to Workday. That was not an improvement.
