Abstract - As the world is technologically advancing, the
desire to reduce human efforts is at its peak. Same is the case
with the field of shopping. Earlier, shopkeepers used to
manually arrange the products chosen by customers and
would do the bill calculation manually, too. But with the birth
of huge supermarkets and shopping malls, manually
arranging and handing of products to customers as well as
manual bill calculation seemed impractical and impossible.
Thus, Barcode based shopping came into existence. But it too,
has its own limitations and there is scope for development. In
the era of “smart”, we need to up the game for shopp ing as
well and switch to smart shopping. This project shall result
into a new shopping experience and shall reduce the efforts
made and the time spent by an average shopper to a
considerable extent. This project might also felicitate the
emergence of an automated shopping system.
Key Words: Shopping, Smart Cart, Arduino, RFID, Visual

1. INTRODUCTION
Presently, the shopping system used in the shoppingmallsis
the Barcode System. This system has replaced the previous
manual system but has limitations. To begin with, barcode
system requires the barcode on the products tobe intheline
of site of the barcode scanner. Its scanning range is just from
a few inches to a few feet. A barcode scanner can read
products only one at a time. Barcodes define the type of
every product but can’t do it uniquely. Barcodes are read
only type and can’t be overwritten. The barcode systemruns
on optical (laser) technology. Barcodes also require a
considerable amount of man power and human effort.
Barcodes can get damaged easily. Not only this, the current
Barcode system requires the customer to stand in long
queues in order to get their products scanned and their bills
generated. This process can prove to be tiresome and it also
consumes a lot of time of the customers, thereby adding to
their frustration. With so many disadvantages to it, Barcode
system is still in use. It is obvious that there is a need to
bring on a smarter and a more efficient system
Smart cart using Arduino and RFIDisanewadvancement
in the field of Supply Chain Optimization. This system shall
not only eradicate the long queues in supermarkets and
malls but also save a lot of time for the customers. The
system also helps the customer in money management. The
system uses RFID tagsin the place of Barcode tagswhichare
much more efficient and powerful when itcomestoscanning
of products. The device developed using Arduino and RFID
shall be installed on the shopping cart or shopping basket
and the customer shall scan their products themselves and
the total generation shall happen on the cart itself. This shall
also give an idea to the customers on how much their
particular shopping session shall cost them. Hence, time
management and money management, both shall be taken
care of.
The paper is ordered into five segments. The first segment
gives a quick introduction about the system. The second
segment is about shopping systems and the study of related
existing systems. The third segment details out the
implementation of the system. The fourth segment presents
the results obtained using the Arduino and RFID containing
device. Finally, the conclusion provides the summary and
future scope about the system.
2. LITERATURE REVIEW
In the Literature review, we shall be discussing about the
different characteristics of the project by taking referenceof
the existing projects that are resemble the working of the
current project.
Iswarya.C, Josuva.D, Vasanthakumar.R [1] have stated that
even though substantial research has been carried out on
applications related to Supply Chain Optimization, yet there
is insufficiency of understanding of essentials and the
advantage of further organizing and managing the data
within business intelligence infrastructures that allow
distributing, integrating and inspecting RFID data.
Although the system has been proposed by them and
explained well but they have not implemented the system
and therefore, the results coming out of their proposed
system is unknown and cannot be compared.
The usage of RFID tags and reader makes the system pretty
efficient when it comes to the scanning of products.
According to Ashmeet Kaur, Avni Garg, Abhishek Verma,
Akshay Bansal, Arvinder Singh [2], if you are to scan 10,000
items, the time taken by a barcode system shall be 53 hours
but the time taken for the same number of items by a RFID
system is just 2 hours. This goes to explain how productive
RFID systems are as compared to the existing barcode
system.
If you have a look at the research work and proposal paper
of Tanushree, Siddharth Yadav, Saksham Aggarwal, Sagar ,
Mohit Yadav , Neeraj Gupta , Shruti Karkra[3], you shall find
that the usage of a RFID based system shall not only reduce

the hassle that we get to see in supermarkets but it shall also
eliminate the wastage of paper making the system
economical as well as environment friendly.
Areeb Asif, Bhavana Singh, Ayush Kr. Sonkar, Hardik Dua,
Preeti Dhiman[4] say that one of the many problems faced
by supply chains is the maintenance of dealing records and
the lack of live inventory lead to problems such as products
being unavailable for sale, and gradual but painful loss of
customers.
According to Muhib A. Lambay, Abhishek Shinde, Anupam
Tiwari, Vicky Sharma[5], the RFID system enables the
retailers to get several additional details about the product
as compared to the Barcode system.
Therefore, when it comes to efficiency and accuracy, RFID
systems prove to be a better option compared totheexisting
Barcode System.
3. HARDWARE AND TECHNOLOGIES USED
Arduino and RFID are two of the major components of the
system. Let us study each of them in detail.
1. ARDUINO
Arduino is basically a software aswell as a hardware project
that doesn’t just design but also manufactures single-board
microcontrollers as well asmicrocontroller kitsfor building
digital and interactive projects and systems.
There is a vast variety of Arduino available. Dependingupon
the requirement of the system or the project, a suitable
Arduino is chosen.
Following are few of the different kinds of Arduino boards
available in the market:
-Arduino Uno
-Arduino Mega
-Lilypad Arduino
-Arduino Leonard
-Arduino Due, etc.
Fig -1: Types of Arduino
The coding of these microcontrollers are done in a software
environment which is again known as Arduino. It basically
uses C/C++ as the coding language and has a vast library of
functions and prototypes that are helpful while writing an
Arduino code.
2. RFID
RFID or Radio Frequency Identification is nothing but the
use of radio waves to read or save information/data in a
RFID based tag. The RFID tags consist of two major
components, that are, a microchip for processingandstoring
information, and an antenna for transmitting as well as
receiving the radio frequency signals.
There are two kinds of tags: battery powered RFID tags and
passive RFID tags. The battery powered tag has a small
battery embedded inside it that gives the tag power to
receive or transmit the information stored. In case of the
passive tags, the interrogator usesitsown power to readthe
information present in the tags.
RFID readers are used to retrieve the information that is
stored inside the RFID tags. The reader consists of a
transmitter that transmits the signal to tag, asking for
information and the receiver retrieves the information
present in the tags.

4. SYSTEM ARCHITECTURE
Smart Cart using Arduino and RFID is an efficient system
when it comes to scanning of products, bill generation and
payment. It uses an Arduino chip, a RFID reader, an LCD,
buzzers, capacitors, buttons, etc. and also RFID tags to be
attached on the products.
The RFID reader shall be used to scan the RFID tags present
on the product and all the information receivedfromthetags
shall be stored in the Arduino chip. The system shall have 3
buttons- total, delete and bill button. The product can be
directly scanned by the reader and if the customer wishesto
remove any product, they just have to press the delete
button and scan the product again. The product shall be

deleted. If the customerswish to see the total, they can press
the total button and the total shall be displayed. While
making the payment of the bill, the customers just has to
press the bill button after connecting the USB to the billing
section and their bill shall be automatically generated in the
admin’s system.
The following block diagrams give a brief idea about the
connections and the working at the trolley side aswellasthe
billing side.

5. IMPLEMENTATION OF THE SYSTEM
Here we shall discuss, step by step, about how we
implemented our system
5.1 Designing the Circuit
For designing the circuit, we used a circuit a circuit-
designing software known as DipTrace. DipTrace is an open
source software that enables us quick and easy designing of
circuits.
Fig -5: Circuit Designing in DipTrace
5.2 Building the Trolley Section
Here, we used the different necessary components such
as the LCD, Arduino, RFID reader, capacitors, buzzers, etc.
The design obtained from DipTrace shall be converted
into a physical circuit. This trolley section shall be installed
on the shopping cart or basket and shall be operated by
the customer.

7. CONCLUSION
“Smart Cart using Arduino and RFID” has been successfully
implemented. This system is not only effective ineradicating
the long queues but also manages the budget of the
customer. This system is automated and far better than the
existing Barcode system. With new technologies rapidly
making every walk of life smart, shopping should be made
smarter too. The system also has a very quick and easy
billing option.
8. FUTURE SCOPE
The transferring of information from the trolley/basket to
the Admin’s system can be made wireless instead of using a
USB. Also, with emerging technologies, the movement of the
cart can be automated, too. Hence, this system has a number
of future applications and can be the basis of some advanced
inventions in the future.
