Introduction
In the fast moving world of today’s technological innovation, the introduction of Just
walk out technology has been a revolutionary experience for the shoppers. This technology is
being used by all major shopping giants that include Amazon and eBay. The major advantage of
this technology includes reduction of the time that is involved in the process of shopping
(Sanders 2016). The aim of the current study is to analyze the existing literature related to just
walk out technology. The application of the same will be critically evaluated in the context of
everyday shopping experience.
This technology will have wider application in the near future. Hence, it is essential to
focus on the future research work that helps to improve upon the application of the technology
for better level of shopping experience.
Use of RFID technology in Retail business
In order to improve upon the operation functional capability of retail business, use of
advanced technology is highly recommended. From the research of Lee and Lee (2015), it is
clear that nearly 73% of the retailers all over the world has implemented the technology of Radio
Frequency Identification (RFID). This has aimed to track every product with detailed
information. The customers also get the opportunity of interactive experience that is needed to
get the idea about the product description. The customers can also get the experience of virtual
shopping that is needed as a part of product promotion.

Vlachos (2014), has added that most of the retailers are aiming to reduce the time that are
involved within the shopping process. The process of automation needs to be included within the
retail shopping. It will therefore be possible to enhance the operations of the ecommerce section.
The implementation of the RFID technology, the retailers have to install the instruments of senor
and CCTV cameras. This will ensure that there is maximum possible security for all the products
are available within the stores. The best application of the RFID into the retail business is related
with the fact that it can help to deal with the issues of products going out of stock. The retail
companies will also get the opportunity to track the customers and thereby help to maintain
relation with the customers. Hence, this will make it possible for the company to retain the
customers using the elements of digital marketing.
Venkatesh (2016), has mentioned about the fact that with adoption of RFID within the
retail units, within the operational sectors, the companies have to bear an extra cost for the initial
infrastructure. This is one of the major issues that enforce the retail industries to increase the
prices of the products.
Application of Just Walk out Technology
According to Pyshkin and Korobenin (2017), the Just Walk out Technology can be
regarded as one of the latest examples of the innovation that are being implemented in the
business operations especially within the retail sectors. In most of the cases, this form of
technology is being applied on case of automatic driving cars. They are also used in the
experience of online shopping, where the shoppers are able to easily choose on to their desired
products according to the availability and make online payment.

Onto the retail industry, this technology was initially introduced by the Amazon, under
the official name of Amazon Go. In a physical retail store the Just Walk out Technology can be
used to be one automatically detect a product that are being taken from the retail store. The
element of virtual cart is considered to be crucial as it can keep track of all the items that are
being picked or returned by individual customers. After the end of shopping, the virtual cart
automatically calculates the total billing amount that is then deducted from the e-wallet of
respective customers.
Turkle (2017), has mentioned about the sensor fusion technology that are being used for
the purpose of Just Walk out Technology. This principle helps in the process of dead reckoning
that is used to track the movement of every item. This principle is followed with the help of the
GPS tracking system. Additional sensors are required in the matters related with detecting the
signals and process the data that are obtained from each item codes. This concept of combining
data of accelerometer and gyroscope that are essential part of GPS tracking Technology forms
the main principle of sensor fusion. This type of technology is mainly required in robotics and
industrial control of data processing system. Hence, in order to understand the application of
sensor fusion it is essential to realize the strengths and weakness of GPS tracking Technology
(Lee, Tewolde and Kwon 2014). As the two sensors of gyroscope and accelerometer are fused
together, it is possible together why the range of data of an item in respect to their position. It is
also possible to yield optimum results that are related with maximum level of frequency.
Deep learning is another mode of technology that is applied in Just Walk out. The
principal for this technology has been inspired from the neural connection of human brain. It is

essential to process the complex level of data that are used within the technology of GPS
tracking system.
Main component of the Planning can also help the machines of Just Walk out Technology
to deal with the neural environment. Hence, it will be possible to recognize each level of
hierarchical data needs to be processed (Feng et al. 2016). The principle of deep learning is
highly implicated in the matters of modern day Medical Technology.
Computer vision is another important principle that is imposed to deal with the matter of
computer science. This process can help to get the data from virtual images of the product.
Advanced level of software used for this purpose. The main function of the program is to search
for computer images that are relevant to every item that are being sold in retail stores. Hence it
will be possible to identify an item based on the virtual image and position. This technology can
also be enhanced with support of augmented reality, where it is possible to easily identify items
of similar shape and dimensions.
Application of Just walk out technology in Amazon Go
Application of the latest technology in retail service Amazon go has been regarded as the
grocery store which is going ahead of its time. In 2016, Amazon revealed the prototype virtual
reality stores that are adopted with Just Walk out Technology. This process of automatic
shopping had been regarded as one of the Revolutionary concept of the current age.
The customers are able to save quite valuable time, which are required for the process of
billing. The deduction of the shopping amount is being done from the e-wallet of respective
customers. The technology of Just Walkout has been used in collaboration with RFID to process
advanced level of information that is needed to identifying any item in the physical retail stores.

The first outlet of Amazon goes mainly consisted of grocery products. The total area of the store
was of 1800 square feet, which consisted of self-driving vehicles for transportation of items.
With the help of advanced technology it is possible to track every item within the huge retail
store (Business Insider, 2018).
The initial step of purchasing an item from the Amazon Go store is to install the Amazon
app can create a user profile. The Smartphone of every individual user will act as scanning
device that needs to be checked during the entry of the store. The smart phone is then is kept
inside the shopping bag, where every items an individual desired to kept is being stored. Through
the phone it is possible for the customer to view the virtual position of every item within the
store.
According to Charniak et al. (2014), element of artificial intelligence is one of the major
element for Just Walkout Technology. Computer software can process the advanced level of
information that are being used by the artificial intelligence. Aspect of computer vision is used
for this purpose in order to successfully check every item within the store.
Conclusion and Existing Gaps
The Just Walk out technology is regarded as one of the major achievements of modern
innovation that are used in retail shopping experience. The major advantage of this technology is
associated with saving of time for the customers, as the entire process of purchasing and billing
are done through tracking Technology using barcodes and scanners.
The sensor fusion technology is one of the most advanced forms of principles that are
being applied in the given case. This combines the technology of gyroscope and accelerometer in
order to process advanced level of data for automatic tracking.
