How RF-Attendance System Works?

In LF – Low Frequency Attendance system, low cost LF card Readers are mounted either in each class room or shared between two or more class rooms or at common entrance. Student shows his LF ID card to LF Reader to mark his arrival & departure. The read range is simply 5 centimeters. In one minute, one Readers reads around 15 students.

  • RFID device installed at various locations & are connected with the RFID Attendance Server housed within the campus.

  • Every Student is given RFID ID CARD.

  • Student shows RFID ID Cards to Reader in every lecturer ever day.

  • Data is transferred to attendance server every 10 mins.

  • Faculty gets list of absent roll numbers before end of lecturer & faculty can verify an equivalent.

  • The Attendance record is updated on Attendance web server. Parent & student can log-in and consider attendance or apply on-line for leave in order that campus is conscious of leave beforehand.

  • They can also check Home work given to their ward.

Installation Of RFID Readers

In following section this process is described in further details.

  • Class Room : Normally one device per 50 students in school with a minimum of two devices during a class to avoid any inconvenience if one device fails.

  • Lab : One device per Lab of fifty students.

  • Library : Minimum 4 devices at different location.

  • Mess : One device per 50 students.

  • Gym : Two devices.

  • Fess Counter : One device per counter.

  • Campus Gate : Two devices per gate.

  • Bank , post office, Canteen, Store sin Campus : One device per unit

Networking With Attendance Server

These devices are connected to the RFID Attendance server housed within the Campus. The Readers have memory of 1,00,000 transactions & albeit net work fails for temporarily, the Attendance data is stores on Readers. As soon as network with Attendance server is established, Attendance server reads the info from Readers & updates in its own data base.

Printing & Tagging Of RFID ID Cards For Students

camera

a) Capture Student’s Photo : Student’s photos are often captured in two ways. Either by scanning of scholars photo submitted by the scholar along side the shape or by asking student to submit scanned image of his photo or by having a photograph session for all the scholars on the day of admission.

camera

b) Capture Student’s Signature : Student signature are often captured either by scanning his signature from form or asking student to check in Digital signature pad.

camera

c) Scan left thumb impression : Student thumb impression can be collected using a Thumb device at the time of admission.

camera

d) Other information of Student : Other information of student which is to be printed are often taken from our MIS. the essential information required is complete name of student, his course, his year & section, mobile no., blood type , Address for communication, Emergency number for contact

camera

e) Printing RFID ID Card plastic card printer : Once the data is compiled & ID card format is designed, Student ID cards can be printed using Plastic card printer. The advantage of printing with plastic card printer the printed matter is all weather proof & colors will remain constant for quite long period as compared to Laser / inkjet printers.

f) Tagging of ID Cards & Registration in Attendance devices : Each Printed Id card is to be Tagged attending MIS. this suggests the unique EPC – Electronic Product Code of RFID ID card is to be assigned thereto student record within the MIS. This process is named as Tagging. Once the tagging is completed , all the EPC codes tagged are transferred to all or any the LF card Reader devices through Attendance server. this is often ID Card Registration process.

g) Registration of Thumbs: Thumb impression of individual student are often captured & registered employing a Biometric Thumb Reader device. This thumb impression image is stored on Attendance Server & is assigned (tagged) to ID no. of student in MIS. Subsequently this Thumb impression image is transferred to all or any the Attendance devices at a time using RF-Attendance MIS. therefore the Student thumb is now registered on all the biometric attendance device within the Campus.

Attendance In Class

First faculty will show his RFID ID card to the Reader and this may start the attendance process of that lecturer. Student will mark their attendance by showing his / her RFID ID card or by putting thumb on biometric device. The over all process should take time below 5 mins which is a smaller amount than the time required by faculty for taking the manual utterance within the class. The time-frame for open for marking the attendance by students are often fixed by college Administration say 10 mins maximum. therefore the student coming after 10 mins are going to be marked as absent & college administration has record of such late comers.

Attendance Editing

After 10 mins, faculty get a SMS showing total count of absent numbers & list if absent roll numbers. Faculty can verify overall accuracy and may also verify absent roll numbers. Students attendance might not get marked on RFID Reader thanks to anybody of the subsequent Reasons.

  • Student may forget to bring the RFID ID card

  • His card is mail-functioning

  • Reader is locked

  • Thumb impression isn’t recognized by Reader

  • Student thumb / ID Card isn’t registered with attendance server

  • Student may come to classes beyond stipulated time-frame

  • Any other un-known reason

It may happen that student has marked his attendance went faraway from the category without attending the complete class and thus faculty may wish to mark him absent. Therefore Faculty can edit wrong / proxy attendance or mark a students Present who has not brought ID cards

CCTV Camera In Class-Room :

To avoid damage to RFID Attendance Reader Devices & to avoid proxy attendance and to avoid late attendance, CCTV cameras are often installed. this may be of great help just in case of any damage to devices or to analysis proxy / wrong attendance. However this might not be a price effective solution

SMS / Email To Students & Parents:

Daily auto SMS / email are often sent to student at a hard and fast time say (7:30 within the evening) stating classes & labs attended by him and places (Library, Canteen, Gym, Hostel, Bank , post office…) where he has visited. If the scholar is absent for quite say three days, SMS may got parents. Weekly SMS could also be sent to parent informing his absentee within the classes. of these SMS / email are customized as per need of the Institutions.

Attendance Web Server:

The Attendance record is updated on Attendance web server. Students & Parents can log-in and consider attendance or apply on-line for Leave in order that Campus Administration is conscious of Leave beforehand.
