There is a really good spreadsheet that a team posted on CD a while ago. I cannot find the post, but our team has used it for the past 3 years. Everyone gets a password and just types the password into a green cell, and it serves as the clock-in/clock-out. I don't have my flash drive on me right now, but I will upload the file when I find it.
EDIT: I found the CD thread on this topic
