Scintillating Billing Trolley With Assemblage Of Rfid

Published Date: 02 Nov 2017

There has been a tremendous increase in the rush of the

people in the shopping malls which in turn causes long

queues for the billing and payment procedures. This has

resulted in the loss of the time and efficiency of the mall

management. Our idea is to develop such a system which

will drastically reduce the billing time and increase the

efficiency of the management. In our system of

Scintillating Billing, we will use the RFID tag and the

Zigbee for fulfilling the idea. The RFID tags will be placed

on the product. Whenever the customer puts a product into

trolley it will get scanned by the RFID reader and product

price and cost will be displayed on LCD of the trolley .The

Zigbee will be used to transmit the data from the trolley to

the billing computer from where the final bill will be

generated. This will greatly enhance the current billing

system of scanning the each barcode of the product.

I. INTRODUCTION

Core functional idea of our paper is based upon the lines

of the “SCINTILLATING BILLING TROLLEY WITH

ASSEMBLAGE OF RFID AND ZIGBEE” used in the

Malls and Shopping Centers. In the traditional method of

Barcodes; that has been in existence for many years and

being used by departmental stores and supermarkets to

manage purchases of merchandize by customers and keep

track of inventory. However, the barcode system is no

longer the best way to business operation. Customers are

tired of waiting in long, slowly moving checkout line in

departmental stores, especially during holidays and

discount offers. With the decrease of prices through

innovation of technology and large-scale production of

semiconductors and wireless components, there has been a

search for new markets in which semiconductor chips can

be used for achieving higher efficiency. This has led to the

use of RFID [Radio Frequency Identification] [4, 6].

In this paper we are using RFID technology for making a

scintillating billing trolley. A device “BILLING

TROLLEY” also called as “Smart Trolley” is an

information storage system. Here the system parameters of

a Scintillating Trolley like products name, products

amount, company name etc. are continuously recorded.

The system displays as well as announces the name of the

product and cost.

This “SCINTILLATING BILLING TROLLEY” is also

applicable for various applications and using proper

interface the recorded data can be downloaded and

transferred to a computer. The trolley being wireless

consist of ZIGBEE module hence free to move in large

area. The system is an efficient means for a commercial

purpose as it is less time consuming and easy to control

[2].

A shopping mall or shopping centers a set of buildings

with retail shops with interconnecting walkways enabling

visitors to easily walk from floor to floor .Research shows

that there has been a speeding growth in the number of

shopping malls in India from late 2000 to early 2005.

Within 5 years total number of malls in Mumbai has share

of 31% and then Delhi, which has a share of 21% with 360

malls anticipated in India by 2007 and 600 malls by the

end of 2010. [9].

The growth was fuelled by rising incomes, greater

availability of credit and evolving lifestyles. Purchasing

and Shopping at big malls is becoming daily activity in

metro cities. We can see big rush at these malls on

holidays and weekends. This crowd becomes huge when

there are special offers and discount. People purchase

different items and put them in trolley. After total purchase

one need to go to billing counter for payments. At billing

counter the cashier prepare the bill using barcode reader

which is very time consuming process and results in long

queue at billing counter.

The past two years have witnessed an explosion of

interest in radio-frequency identification and supporting

technologies, due primarily to their rapidly expanding

using tracking grocery products through the supply chain.

Currently such applications monitor store-keeping units

(SKUs) rather than individual goods, as the relatively high

cost of RFID deployment and the very low profit margin

of supermarket products make item-level tagging

impractical.

Yet, economic and technical concerns aside, it is easy to

envision a supermarket in which each item is tagged with

an RFID label and all shopping carts feature RFID readers.

The carts could potentially include onboard computers that

recognize products placed inside and that display

information and promotions retrieved wirelessly from the

system back end. Item-level deployment of RFID

technology would also allow for quick checkout aisles that

scan all products at once and thus eliminate queues, which

are consistently reported as one of the most negative

aspects of supermarket shopping. A simple extension of

this system would be to embed RFID devices in

consumers' loyalty or frequent-shopper cards to identify

individuals. This could expedite system login and charge

the shopping cost directly to the customer's account at the

point of sale-unless removed at the POS. [5, 6].

II. PRESENT SYSTEM

2.1 CURRENT BILLING METHOD

Currently available method in shopping malls is barcode

method. In this method there are barcode labels on each

product which can be read through specially designed

barcode readers. A barcode reader (or barcode scanner) is

an electronic device for reading printed barcodes. Like a

flatbed scanner, it consists of a light source, a lens and a

light sensor translating optical impulses into electrical

ones. Additionally, nearly all barcode readers contain

decoder circuitry analyzing the barcode's image data

provided by the sensor and sending the barcode's content

to the scanner's output port.

When we select any product for buying we put it in the

trolley and take it to the billing counter. The cashier scans

the product through the barcode scanner and gives us the

bill. But this becomes a slow process when lot of products

is to be scanned, thus making the billing process slow.

This eventually results in long queues. [7].

2.2 COMPARISION OF BARCODE & RFID

If compared, RFID technology is found to be more

comprehensive than barcode technology [8].It is possible

to read RFID tags from a greater distance. An RFID reader

can access the information of the tag from a distance of

around 300 feet, whereas barcode technology can't be read

from a distance of more than 15 feet. RFID technology

also scores over barcode technology in terms of speed.

RFID tags can be interpreted much faster than barcode

tags. Barcode reading is comparatively slower because it

requires a direct line of sight. On an average, a barcode

reader takes around one second to successfully interpret

two tags, whereas in the same time the RFID reader can

interpret around 40 tags.

RFID tags are well protected or either implanted inside

the product, and hence is not subjected too much wear and

tear. Interpreting a barcode requires a direct line of sight to

the printed barcode, because of which the barcode is

printed on the outer side of the product, and is thus

subjected to greater wear and tear. It also limits the reutilization

of barcodes. As barcode lacks read and write

facility, it is not possible to add to the information already

existing on it. On the other hand rewriting on RFID tags is

possible [3].Hence RFID is a better alternative to the

Barcode system.

3.2 SYSTEM ARCHITECTURE DESCRIPTION

In our Scintillating Billing Trolley system environment,

each product will have the passive Radio Frequency ID tag

which is bearing a unique Electronic Product Code. This

Electronic Product Code provides the info like name, price

etc about the product.

When the customer will put the product in the

Scintillating Billing Trolley, the Radio Frequency ID scans

the tag and the Electronic Product Code number is known

by Radio Frequency ID reader. Radio Frequency ID reader

passes the Electronic Product Code to the ARM 7 microcontroller

where ARM 7 compares the Electronic Product

Code with the database of the system containing various

products. After that the name and price of the product

obtained by the ARM gets displayed on the LCD display

of the Scintillating Billing Trolley, where user can see the

product information [1].

The ARM 7 microcontroller also passes the data obtained

from the database to the Zigbee transmitter from where the

data is wirelessly transmitted to the billing computer. The

master computer receives this data through Zigbee receiver

using Max 323 interface. Max 323 interface is the

interconnection media between the Zigbee receiver and the

computer [1].

IV.MATHEMATICAL DEPLOYMENT

Input:

Xi is the cost of the product in the trolley

M is the number of products(same)

N is total number of products in the trolley

Intermediate Values:

Xf is the cost of product along with its quantity

Xb is the cost of all products

Output:

Total Cost: Xb

4.1 DEPLOYMENT DESCRIPTION

In this mathematical model, Xi is the cost of the

product which will be stored in the product database

of the system. M is the multiplicative factor the same

product. N is the total number of products which will

be required to generate the final bill of the trolley.

The cost of the product is obtained by comparing the

EPC i.e. Electronic Product Code of the tag with the

database. Consider the following example:

EPC code of product: a3424323445

Database info of EPC:

Price= Xi = 10/-

Name: abcd

This information will be obtained while the EPC is

scanned by the reader.

- Now suppose the quantity of product abcd is M = 10.

-Then with the function

Xf = ( 𝑖

=0 Xi * M ) (3)

(Xb) (2)

Xf = (𝑀 ∗ 𝑛𝑖

=0 Xi )) (1)

(Xi, M, N)

Xb = (Xf ∗ 𝑛𝑖

=0 N)

Adding total cost of products

the total of same products will be calculated.

-This will be 10*2 =20.

-This result will be stored in Xf.

- If different products are added to the trolley than

they will calculated by

Xb = (Xf ∗ 𝑛𝑖

=0 N) (4)

-The final result will be stored in Xb, which will be used in

creating the final bill of the trolley.

V.APPLICATIONS

The main application of this system is at shopping

malls to reduce the billing time and enhancing the

shopping joy.

The application is that it can also be used at Jewelers

shop with some modifications.

It can be used anywhere like shopping markets where

the barcodes are used to good solution which avoids

barcode technology.

VI. LIMITATIONS

1. It cannot be used to keep the all sales track and item

availability at the shopping malls.

2. We cannot implement the security regards to theft of

items at malls by using the camera module in trolley level

itself and keeping his track of events.

3. Using text to voice converter, we cannot implement the

voice effect to notify the customer after inserting each item

in trolley.

4. By using the smart card reader, we cannot make system

which is used to billing through credit cards and ATM

cards at trolley itself, and hence we can further reduce the

overall billing time.

VII. FUTURE SCOPE

The future of this system is very bright and progressive

as it is a key to cost savings and efficient management.

Wireless scintillating trolleys can be integrated with Wi-Fi

systems or for that matter even with the internet. In this

way it would ensure a truly, electronic global supply chain

management & inventory management. Moreover the

scope can be expanded even more with slight

modifications in following ways:

1. This technology can be used at airports because of its

wireless nature and its ability to ensure better security.

2. With certain modifications it can be used to track

movement of containers on docks and ports.

3. With the advent of scintillating systems, trolleys will

eventually replace salesmen, hence helping in reducing

final product of goods. As a result, better and more profit

margin.

4. Global sales monitoring and inventory control from a

geographically far off site.

VIII. CONCLUSION

Concluding this paper, we would like to highlight that we

drew the inspiration and idea of this paper after observing

large queues at the sales and billing counters at the Retail

bazaars. While working on this paper we learnt

substantially about RFID technology, embedded systems

and wireless systems, especially Zigbee modules alike.

This system would help in cost saving at the supply chain

level. At the same time it would also reduce the required

no of salesmen. Thus it is truly time saving method and

guarantees the less time consumption out of all present

billing methods.
