he main problem school facing in automatic attendance is efficiency and multiple attendance detect of student. At the time of student leaving from school, bulk students get out from the school gate simple UHF RFID gate or RFID Antenna is not enough to take the attendance and detect RFID tag due to insufficient stack of memory in controller, so here our technology stands.
UHF IMPINJ Controller has 4 port it means we can connect 4 antenna in one controller this makes to detected multiple RFID tag of student ID card. Impinj Controller has a large stack of memory to keep the detected RFID tag no number, it also check repeated detected RFID Tag and send data to the server. After that we detect and check those RFID number and punch attendance and send real time SMS and notification in our IMS android app
