ABSTRACT
Time-Keeping and Attendance systems are of vital importance to institutions. The Bundy Clock is one of the basic means of recording the employees’ time in or out; although more sophisticated technologies are available in the market. This study designs an alternative computer-based system that uses a light sensor to read bar-coded cards as a means of establishing employee identity. The devices used were housed in a log box made of wood. the log box has a slit for the cards to be swiped through. The cards contain different barcodes combinations that correspond to different employees. For the devices to be workable, a Java-based program consisting of three parts-the card reader, the log in or out and the RCX-to-PC communication was needed. The cards and the log box were successfully made. The program on the other hand is still now workable for it lacks the RCX-to-PC communication part. However, the log-in/log-out program can act as a stand-alone program to record the times of logging in/out even without the devices, provided it is a manual method of computer log-in.
