US Patent 7298673 Time attendance clock and system

A time attendance system, including a time attendance clock, designed to be used in harsh conditions, such as outdoor job sites. A portable touch button, including a passively readable code, is brought into contact with the time attendance clock so as to create a time attendance record stored in the clock. Visual indicators and audible notification alert the employee of the acceptance of the act. Periodically, the time attendance records are retrieved from the time attendance clock, such as by using a hand-held electronic device which communicates in a wireless manner with the time attendance clock.
