Abstract - Identification and Authorization of a person is
determined using his personal metrics. For this specified work
various types of authentication systems are used in the
market, to point out the identity of a human being. Therefore,
biometrics or biometric authentication serves as a type of
gadget that employs the measurement of fingerprint
biometrics of a human body, transforming the security
industry. Manually attendance procedure usually takes lot of
time and also consumes more energy & effort for validating
the attendance data because a large amount of attendance
data will be generated. Therefore, in this paper, a system is
proposed to reduce these problems & level of it & produce
effectiveness of processing student’s data using a system with
the help of a concept & methods of IOT i.e (Internet of Things)
with the fingerprint (biometric) method. Here the student's
data are uploaded safely onto the cloud server & can also be
easily collected as per need. This research paper draws a
picture of how a simpler, easier system can be made to use
student attendance system using Internet of Things (IoT)
Technologies.
Key Words: Biometric, Efficient, Integrate,
Authorization, Authentication.
1. INTRODUCTION
Basic attendance method which is followed in our school
system, where the teacher calls our Roll No or name of the
student & marks his/her attendance respectively. This
usually consumes a lot time & energy. This method becomes
more hectic when there are large number of students are
present in a class Managing this all type of data is veryhectic
and restless thing, One more extra disadvantageisthatthere
is also a chance of marking a fake or proxy attendance of
students Hence this study/model presents a systemthatcan
record the fingerprint of students&usethem wiselytocheck
their attendance for lectures and other types of activities.
Also Biometrics assures the physical presence unlike RFID
card or password security systems which are precarious.
The design of this system proposed in this paper is a
collaboration of NodeMCUESP8266(microcontroller),R307
Fingerprint Sensor module, and an online Google sheets
display. This system requires a connection to a website that
can be gained through Wi-Fi. This R305 fingerprintsensor is
capable of clarifying the finger images within seconds and
also provides the storage capacity of 127 fingerprints.
Here each student will be assigned to a distinct ID number
which is activated duringthe fingerprintenrollment process.
The built-in Wi-Fi module present in ESP8266 is used for
creating a connection so that the end-user can make a
connection with the device. Under this type of process &
working conditions, the deviceisnow efficientofvalidatinga
person by his fingerprint & uploading the respective data
with time in time out to respective, webserver Now below a
brief literature survey narrates the recent studies and
implementation of this similar concept.
1.1 Objective
The main motive of this modelistoavoidfakeattendance,
thus increasing the authenticity of attendance data records,
to reduce the process of manually takingandmaintainingthe
attendance records becomes highly cumbersome.
A system that track records of theattendancemakinguse
of biometric scanners and feeds them securely over cloud.
This Biometric attendance systemisbasedonfingerprint
and wireless techniques which decodes the issue of proxy
attendance and the inconvenience of handling the manual
data of each student.
1.2 Problem Statement
This system prevents from false attendance, much of our
time will be saved & therefore honestly of student
attendance data is also optimized. Spoof is another problem
with the old system. There are several the students who
make fake signs or responds where in some cases where the
students are not present and this method won’t make the
attendance of students reliable.
1.3 Literature Survey
For research by Dhanalakshmi et al. [6] IT Offers research
using fingerprint and Wi-Fi module. Biometric attendance
system is designed and implemented for effective real-time
monitoring and Transparency in managing the physical
presence. Wi-Fi- WirelessFingerprintTerminal(WFT).thisis
the system who is appropriate when implemented in
educational institutions. Everyone has a unique fingerprint
pattern and is used to find the record of a particular
individuals. Student attendance tracking is verified by
Institute.
There are two ways to authenticate fingerprints taken in the
verification process. In firstmethod the organizationCreates

database itself and usesa different approach. secondmethod
is CIDR, student's attendancecanbemonitored,recordedand
sustained withoutanyinterferencefromhumans.Attendance
can be automatically sent directly to students and Parents'
mobile numbers via SMS. It provides transparency as well as
enhanced efficiency. This can help in Managing and
improving in attendance system.
2. PROPOSED WORK PLAN
2.1. The main aim of the project is to automatize
the procedure of attendance
The flow chart will be as follows: -
Chart -1: Flow Chart
2.2 Algorithm
1. System begins.
2. Scans for the Wi-Fi network (if nothing is selected).
3. Connection is established successfully.
4. It starts scanning for the fingerprints when the
connection is established successfully.
5. Students can scan their fingerprints now.
6. Selection of choice of enrolling a new fingerprint or
deleting the previous ones.
7. When it evaluates and matches any student’s
fingerprint image, it uploads their fingerprint ID to
the google spreadsheet.
8. As and when the server receives the finger print
data from its system, it upgrades the
presence/attendance of the student.
3. System Design & Components
a) NodeMCU ESP8266 - NodeMCU Microcontroller
Unit is an IOT platform that runs on ESP8266. It has
one analog pin (a0) and nine digital pins (D0-D8).
The input voltage is between 7-12V and a operating
voltage is 3.3V. It has flashmemoryof4MBandclock
speed is of 80 MHz It has also two control pins i.e.,
EN,RST which resets the microcontroller.Ithasalso
16 GPIO i.e., general-purpose i/p, o/p pins on the
board.
b) R307 Fingerprint Sensor - R307 a fingerprint
sensor who has TTL UART for the direct
connections. It has a storage capacity of 1000
fingerprints. Its operatingvoltageisbetween4.2-6v
Dc. R307 has 0.3sec scanning speed. It follows one-
to-one approach (1:1) and one-to-many (1: n)
approach. The specialty of this module is it
consumes low power, it costs also low as compared
to others.
c) Breadboard - Breadboard is type of toolorwecan
say a regular rectangular type board with large
number of holes knows as strips presentonit.These
strips let us to insert any type of components into it
to check or analyze an earlyversionofanyelectronic
circuit. There also latest types of breadboards
available in the market ofdifferentshapes,sizes,and
color. There are also numbers, letters written in the
top if each row strip just for reference.
3.1 Software
Google Spreadsheets - Google Sheets are a kind of
spreadsheet programs which are incorporated as part of
open source, web-based document editors which are being
offered by Google. Google Sheets is type of a application
which is totally online web-basedthatgivesaccesstousersto
build, upgrade and reform the spreadsheets and update the
information simultaneously.

This google online spreadsheet application enables users to
build, upgrade and reform the spreadsheets. These types of
Sheets are often compared to Microsoft Excel, as both of the
applications are used for homogeneous purposes.
How to use Google sheets? (Steps)
The Users have an access and can create on their own and
also can modify the spreadsheets via the Google Sheets also
they can access it through mobiledevices-basedapplications
or running on iOS devices. To get accesstotheGoogle Sheets,
one should have valid email ID is required. Sheets also has
the following functions: -
 The data here is available in the form of tables
where we can construct and handle data.
 Examine - They can conceptualize the given
spreadsheet data into various forms like pie charts,
bar graphs and various forms of tables.
 Share – Users can easily share their sheets or their
documents with anyone or can enable privacy in it
for security purpose.
 Printing – There are also other options available to
import the Sheets files into otherdocumentformats
like Microsoft Excel, Microsoft Word, Microsoft
PowerPoint, PDF reader and etc.
 It is also a kind of similar to Microsoftexcel,because
most of the spreadsheet’s functions are same.
3.2 System Implementation
The proposed method in this paper is a design of portable
Biometric system which enables a server to accept the
fingerprint ID. The data is directly logged to a computer in
excel file which is running the client application. This
completely eliminates the need of storage device in the
design. The other improvementisandtimeanddateisadded
to the logged data. This also eliminates the RTC hardware.
Battery power is the most importantresourcefora handheld
device. These two improvements help to reduce the power
consumption which is provided by a battery.
The design methodology is easy to understand with a block
diagram representation as in Fig. The design is mainly
separated into four parts, i.e., the power supply section,
control(microcontroller) and display section, biometric
scanner section, and IoT communicationsection.Thecontrol
and display section is formed by NodeMCU microcontroller
and Google sheet The biometric scanner section is anoptical
fingerprint scanning module R305, and Wi-Fi ESP8266
module is the IoT communication section. Thepowersource
is a 9 V Li-ion battery with 3.3 and 5 V regulators, is the
hardware prototype setup of device which shows each
section mentioned above.
4. Applications –
The system will also be used as biometric attendance of
students. This types of techniques are often used for real
time monitoring of presence of students and helps in
maintaining the attendance records in real time. It can be
used for safety purposes where high-level of security is
desired. The system can be improved by enclosing it in a
plastic covering. This would makeitmorecompact&reliable
to use in a classroom setting.
It can be further improved in domestic as well as industrial
application too. It can also be improved to fit the corporate
environment. Usually, biometrics are also used in the legal
process or related to some government work also. It is a
basically efficient and low-cost embedded platform with
easy report generation facility available.
5. Conclusion
The procedure of manuallytakingattendanceisverydifficult
and very time consuming. To avoid this, Biometric
Attendance based on IoT comes in the picture. This IoT
based system supports biometric identification and has a
capability of recognizing features automatically. It is an
open-source system and user friendly because of lack of
complexity.

The system can be used almost at each place such as
classroom for student's attendance, In MNC companies to
keep the record of employees/workers, etc. The IOT system
can further help in calculation of attendance percentageand
can help admins to keep record.
