Internet of Things Based Smart Vending Machine using Digital Payment System

The advent of the Internet envisions a cashless society by enabling financial transactions through digital payments. Significantly, the emergence of coronavirus (COVID-19) disrupted our traditional cash handling means and triggered an inflection point for switching towards contactless digital payments from physical cash payments. Furthermore, Internet of Things (IoT) technology escalates digital payments to the next level by enabling devices to render goods and services without requiring any human interaction. This research proposed an IoT-enabled cashless vending machine that incorporates both cloud computing and payment gateway for ordering and purchasing items through digital payment systems by using a mobile application. The system enables a pre-installed mobile application to scan the Quick Response (QR) code attached to the body of a vending machine, opens the portal of a web-based virtual machine through the code, allows user to choose and order items from the virtual vending, initiates and authorizes a digital payment through an IoT gateway installed inside the physical vending machine by establishing a connection between user's and vendor's financial entities, and finally, dispenses the ordered items by unlocking the shelves of the vending machine after the successful payment transaction. It operates in the Arduino platform with an ATmega 2560 Microcontroller and Esp8266 Wi-fi module as hardware components, mobile application software, and payment gateway API. The system performed an average response time of 14500 milliseconds to pick a product after running 150 consecutive API test calls. This result shows a satisfying time for enhancing customers' buying experiences with digital payment systems and a customizable and cost-effective IoT-based intelligent vending machine to introduce for mass production

The Emerging Internet of Things Marketplace From an Industrial Perspective: A Survey

The Internet of Things (IoT) is a dynamic global information network consisting of internet-connected objects, such as Radio-frequency identification (RFIDs), sensors, actuators, as well as other instruments and smart appliances that are becoming an integral component of the future internet. Over the last decade, we have seen a large number of the IoT solutions developed by start-ups, small and medium enterprises, large corporations, academic research institutes (such as universities), and private and public research organisations making their way into the market. In this paper, we survey over one hundred IoT smart solutions in the marketplace and examine them closely in order to identify the technologies used, functionalities, and applications. More importantly, we identify the trends, opportunities and open challenges in the industry-based the IoT solutions. Based on the application domain, we classify and discuss these solutions under five different categories: smart wearable, smart home, smart, city, smart environment, and smart enterprise. This survey is intended to serve as a guideline and conceptual framework for future research in the IoT and to motivate and inspire further developments. It also provides a systematic exploration of existing research and suggests a number of potentially significant research directions.Comment: IEEE Transactions on Emerging Topics in Computing 201

Benefits and Challenges of Internet of Things for Telecommunication Networks

Recently, Internet of things (IoTs) has become the main issue in designing monitoring systems such as smart environments, smart cars, and smart wearable devices. IoTs has transformed the life of people to be more adaptable and intelligent. For example, in a healthcare monitoring system, using smart devices will improve the performance of doctors, nurses, patients, and the healthcare industry. The IoTs revolution is known as the fourth industrial revolution and would change the way humans interact with machines and lead the way to a high-technology machine-to-machine interaction. In fact, almost every device around us would be connected to Internet, collecting and exchanging data with other devices on the cloud. In this chapter, we will introduce the benefits of IoTs on telecommunication networks and its challenges to give a complete overview for researchers to know how to improve our life and society by building smart IoTs systems

Understanding Current Trends on Internet of Things - An Overview

Internet of Things (IoT) is the concept of providing automation by adding some level of digital intelligence to physical devices. It relates to the activities of data sharing, data controlling and automation among billions of physical devices around the world. Lower price of processor, wireless network and inexpensive technologies result in turning any object into the part of internet. Smart environment equipped with sensors provide automation in interrelated computing devices, machines, animals and human resources. Data collected from different smart devices is being interpreted by different researchers for analyzing in order to make better business decisions. This review paper has shown experimental research on the Internet of Things published since 2013. We summarize different applications of IoT in various fields and highlighted various issues related to different factors of IoT enabled devices

Sensor Networks and Their Applications: Investigating the Role of Sensor Web Enablement

The Engineering Doctorate (EngD) was conducted in conjunction with BT Research on state-of-the-art Wireless Sensor Network (WSN) projects. The first area of work is a literature review of WSN project applications, some of which the author worked on as a BT Researcher based at the world renowned Adastral Park Research Labs in Suffolk (2004-09). WSN applications are examined within the context of Machine-to-Machine (M2M); Information Networking (IN); Internet/Web of Things (IoT/WoT); smart home and smart devices; BT’s 21st Century Network (21CN); Cloud Computing; and future trends. In addition, this thesis provides an insight into the capabilities of similar external WSN project applications. Under BT’s Sensor Virtualization project, the second area of work focuses on building a Generic Architecture for WSNs with reusable infrastructure and ‘infostructure’ by identifying and trialling suitable components, in order to realise actual business benefits for BT. The third area of work focuses on the Open Geospatial Consortium (OGC) standards and their Sensor Web Enablement (SWE) initiative. The SWE framework was investigated to ascertain its potential as a component of the Generic Architecture. BT’s SAPHE project served as a use case. BT Research’s experiences of taking this traditional (vertical) stove-piped application and creating SWE compliant services are described. The author’s findings were originally presented in a series of publications and have been incorporated into this thesis along with supplementary WSN material from BT Research projects. SWE 2.0 specifications are outlined to highlight key improvements, since work began at BT with SWE 1.0. The fourth area of work focuses on Complex Event Processing (CEP) which was evaluated to ascertain its potential for aggregating and correlating the shared project sensor data (‘infostructure’) harvested and for enabling data fusion for WSNs in diverse domains. Finally, the conclusions and suggestions for further work are provided

Working With Useless Machines: A look at our shifting relationship with ubiquity through personal assistants

This research explores how a nihilistic approach to the development of personal assistants can problematize the ways these technologies are being brought to market by using the concept of the useless machine. The research is organized around the creation of four prototypes: SAD Blender, Home Hub, Calendar Creep, Fortune Tasker, and a personal web server named Punchy. Each of these prototypes seek to critique the current corporate agenda of productivity, efficiency, and consumption, by creating machines that have no utilitarian function. This work investigates and defines useless machines in the contemporary context of personal assistants, and documents the development of each of the prototypes and server. Overall the research shows that while its not possible to completely divorce these devices from their parent corporations, they do serve as an important vehicle to explore the changing landscape of ubiquity, and our shifting ability to work and live with these connected object

Perspectives and approaches for the internet of things

Dissertação para obtenção do Grau de Mestre em Engenharia Electrotécnica e de ComputadoresThis thesis was developed based on a scenario in which a CEO of a certain company asked the author to conduct an exploratory work evaluating the potential opportunities and limitations of this emerging area described as the future of the Internet, the Internet of Things (IoT). The objective is thus to provide the reader with a wide view of the vital points for the implementation and exploitation of the IoT, a technology that promises to deliver a new and wider range of applications to the society. In this subject there is a need to gather and organize information produced by several researchers and contributors. Due to the fact of being a new area and researchers work independently of each other, the work is scattered and inconsistencies can be found among different projects and publications. As such, in a first stage some definitions are provided and an attempt to clarify concepts is made. To support and emphasize the exponential growth of IoT, a brief historical overview is provided to the reader. This overview is based on the new trends and expectations that arise every day through news, potential businesses and also in important tools such as Google Trends. Several examples of applications in the context of the IoT, illustrate the benefits, not only in terms of society, but also for business opportunities, safety, and well-being. The main areas of interest to achieve the IoT such as: hardware, software, modeling, methods of connection, security and integration are studied in this work, in order to provide some insight into current strong and weak points. As the Internet of Things become a matter of large interest, various research groups are active in exploring and organizing projects in this area. Some of these projects, namely the ones considered the most important, are also presented in this thesis. Taking into account the facts surrounding this new technology, it becomes quite important to bring them together, clarifying them and trying to open new perspectives for further studies and improvements. Finally, in order to allow a practical evaluation of the technology, a prototype is developed around the connection of an intelligent object – a small mobile robot – to the Internet. A set of conclusions and future work directions are then presented which take into account the findings of the bibliographic analysis as well as the acquired experience with the implementation of the prototype
