How to prevent double login

I'm writing a time monitor and I need a way to stop people from clocking in more than once, if you have clocked in already that day I want the system to prevent you from being able to clock in again. Please I need ideas!!!

You're probably writing to a db, just insert a flag that's tripped everytime they clock in. Trip it again when they clock out.
