2.2 IoT in Retail Value Chain

IoT is revolutionizing every aspect of retail be it inventory management, real time

promotions, shelf Management , optimization of store layouts etc .

2.2.1. Inventory Management and Dynamic Merchandising

Retailers face a major challenge of inventory management. IoT helps to deploy sensors like

RFID tags, on products and thus help in realtime tracking. RFID tags on inventory

communicate via cloud to the retailer, thereby helping retailer to analyse the trends and sales

data to anticipate proper stock levels. Moreover customer finds several options to make a

purchase resulting in strong positive impact on customer perception of retailer

2.2.2. Intelligent Digital Shelving

Intelligent digital shelving grab customer attention by playing eye-catching video marketing

various retail products and promotions which helps in increased sales. Brand and price

promotion messaging on a digital signage can generally produce a sales, grabbing customer

attention for new product launches. Further, it helps to reduce operating cost as it eliminate

printed price labels.

2.2.3. Shelf Compliance

Automated shelf compliance solutions use the latest digital image recognition technology to

ensure product placement on store shelves complies with planogram models. At the same

time, retailers can increase revenue by reducing lost sales due to out-of-stock items

2.2.4. Optimizing Store Layouts

Bluetooth beacons inside the retail outlet can track smartphones and record purchasing path

which can help in optimizing layout and provide product or promotional information.

2.2.5. Increased Sales

Retailers use Smart Mirror functionality to read the RFID tags on the hang tags of the product

and thus when customer tries a dress in front of mirror the app communicates with retailer

data centre and thus determines other items that pair with dress. The smart mirror display

those items giving shopper an impression as if he is trying the items. If they are liked the sales

associate is intimated resulting in cross selling and multiple selling.

2.2.6. Enhanced reach through Next Generation Vending Machines

IoT has helped in creating next generation vending machine. These machines can perform

various activities such as monitor level of its inventory, can vary prices based on demand and

inventory,enable predictive maintenance, monitor products condition and can reduce price

accordingly and can also access customer’s past purchases and recommend product right.

2.2.7. Personalized Product Information

Intelligent mobile advertising solution has helped retailers by displaying customized

advertisements to by coalescing mobile data, internet and social media browsing. Further,

consumers can also get customized information based on their interest and thus help in

efficient shopping.

2.2.8. Realtime Promotions

Smartphones are an important key part of IoT. Smartphones are used for sending realtime

promotions based on customer’s shopping history, personal preferences, location etc.

tracking movement of delivery trucks more efficiently. It helps in deciding routes for delivery,

recommends appropriate speed, adjusts storage temperature etc. This leads to reduced fuel

costs, accurate lead time, theft and loss etc

The second part of the research aims at studying technology usage by shoppers.

3.0 REVIEW OF LITERATURE

Shopper behaviour especially with technology like smartphone, along the path of purchase

and relevance of its understanding has been studied by few researchers.

Dholakia,N and Sinha,P.K.(2005) observed shoppers’behaviour in Ahmedabad in both

traditional and new formats .They revealed that in case of traditional format shoppers

generally try to get the feel of product and refrain from browsing. They scan the outlet and

generally do ask for an alternative from retailers. In case of new formats, shoppers browse,

look for various brands ans are even willing to deviate from their list. Infact,some shoppers

make mobile calls to seek advice from family members.

Verhoef, Neslin, and Vroomen (2007) mention that Shoppers generally make a visit to

retailer’s websites befor making a purchase

Kalyanam, Lal, and Wolfram (2008) mention that technologies like RFID, VR, and

mobile technology have provided increased opportunities to retailers to influence shopper

decisions

Mckinsey report ( 2008) Indian shopper do not travel for more than 15 minutes for

regular shopping .They like to see the best brands even if they are not ready to buy them

.They want to check prices within and across stores.

A New York Time article by Rosenbloom,S. (2010) mentioned that retailers are looking

forward to offer real time coupons while shopping, They would offer loyalty cards on

smartphones. Even shoppers are comparing prices & scanning information using their

smartphones.

Huang et al. (2011) show that targeted mobile app promotions based on projected

shopping path of shopper inside store increase shopping time and path length and thus

increase impulse purchase by over 20 percent.

Smith, A. (2013) reveled that while inside store shopper use smartphone to seek shopping

advice from friends and family followed by looking for product reviews and price

comparisons.

4. OBJECTIVES

The study aims to study shoppers’ behaviour using smartphones

5. RESEARCH METHODOLOGY
