Create a setting that allows the web clock to be turned into a kiosk that allows employees to login only using their clock pin. This would create a "kiosk" that all employees can clock in from without entering their username and password. This would be a great alternative to a hardware clock as it could potentially be setup on a tablet or computer for shared access.
Even if it was setup like the web clock for TWP, that they login with user name and password, punch the clock, and are immediately logged out, it would help greatly.
