Teachers use various methods to track entries and exits during class time. Attendance tracking can all be automated using an RFID Reader and RFID Tags. Students tap their RFID Tag on the RFID Reader to record when they enter and exit the classroom. In this project, you will track student arrivals, exits, and their overall time in the classroom.<\/pee>[\/et_pb_code][et_pb_code admin_label=”ph-button-cta: Start” _builder_version=”4.4.1″ box_shadow_horizontal_tablet=”0px” box_shadow_vertical_tablet=”0px” box_shadow_blur_tablet=”40px” box_shadow_spread_tablet=”0px” vertical_offset_tablet=”0″ horizontal_offset_tablet=”0″ z_index_tablet=”0″] <\/p>\n
