Antalet mobiltelefoner har ökat avsevärt de senaste åren. Med detta har även användningsområdena för dem ökat. Ett av dessa användningsområden är mobilbetalning, där mobiltelefonanvändaren kan betala med sin mobiltelefon på samma sätt som om de hade använt ett betalkort. Mobilbetalning är något som blivit stort på flera marknader i världen men inte i Sverige, trots att Sverige är ett land där mobiltelefonanvändningen är högre än i de flesta andra länder. Syftet med denna studie var att undersöka vilka faktorer som spelar in i vad som får svenska konsumenter att använda sig av mobilbetalning och till vilken grad dessa faktorer påverkar deras vilja att använda denna betalningsform. Vi började med att studera vilka faktorer som spelat in i liknande marknader och baserat på dessa presenterade vi ett antal hypoteser för vad som spelar in i adoptionen av mobilbetalning. För att undersöka konsumenternas åsikter använde vi oss av en enkät som spreds på webben och personligen till allmänheten i en stad i Sverige. För att analysera de data vi fick använde vi oss av linjär regressionsanalys. Vi kom slutligen fram till att de faktorer som spelar in i huruvida svenska konsumenter vill använda sig av mobilbetalning eller inte är förtroende, upplevd användbarhet och benägenhet till personlig innovation. / The number of mobile phones has increased considerably in recent years. With this, the uses for them has also increased. One of the applications is mobile payment, where mobile phone users can pay with their mobile phone just as if they had used a debit or credit card. Mobile payment is something that has become big in many markets in the world but not in Sweden, a country where mobile phone usage is high. The purpose of this study was to examine the factors that influence whether Swedish consumers are willing to use mobile payment or not and the degree to which these factors come into effect. We began by studying the factors that played an important role in similar markets, and based on those, we presented a number of hypotheses for what affects the adoption of mobile payment. To examine the consumer views, we used a survey that was spread on the web and in person to the general public in a city in Sweden. To analyze the retrieved data, we used linear regression analysis. We finally came to the conclusion that the factors that influence whether Swedish consumers want to use mobile payment or not are trust, perceived usefulness and personal innovation.

Le début du XXIe siècle se caractérise par l'explosion des échanges via Internet et par la multiplication des objets connectés, au premier rang desquels le Smartphone (apparu en 2007). Autant d'appareils qui permettent de recevoir et d'envoyer des informations sous des formes diverses (messages vocaux, images, vidéos, textes, etc.). Les modes de communication et les usages qui en découlent se sont multipliés et propagés. C'est désormais en milliards que se comptent les utilisateurs de Smartphones. Celte adoption en masse du Smartphone a radicalement transformé les habitudes de tout un chacun, sans distinction de génération, de sexe, de catégorie socioprofessionnelle, de culture, d'appartenance géographique, etc. Envahissant la planète et pénétrant, dans le même élan, la sphère artistique, l'appareil a su se faire adopter par les créateurs, auprès desquels il joue désormais un rôle particulier, voire plusieurs: d'abord sujet de réflexion, Je Smartphone, à la technologie complexe et aux nombreuses fonctionnalités, est devenu à la fois outil de création, lieu d'expérimentation et d'exposition, moyen de transmission et de diffusion ... Connecté et tactile, il a créé une proximité et une relation nouvelles entre les artistes et le public. Bien qu'extrêmement diverses, les pratiques artistiques et les œuvres qu'il engendre n'en forment pas moins un corpus cohérent dont les ressorts communs diffèrent de ce qui caractérise habituellement une œuvre d'art. La force du Mobile An réside dans sa capacité d'adaptation et de métamorphose. Avec lui, l'imagination déborde sans cesse la technologie pour se mettre à la portée de tous. Il est un art démocratique, désacralisé et populaire. / The outburst of exchanges via Internet and the multiplication of connected devices -number one being the Smartphone which arrived in 2007 -characterize the beginning of the XXIst century. Ali these devices enable us to receive or send different forms of information (voice messages, images, videos, texts, and so on). These new ways of communicating and their new uses have been greatly developed and diversified ever since. There are now billions of Smartphone users around the world. This massive use of the Smartphone utterly transformed everyone's habits, whatever the generation, the gender, the socio-professional category, the cultural background, the geographical area ... After flooding the plane! and then ente1ing the artistic sphere, this device has been adopted by artists and is now playing a very special part in their creative process: first mere food for thought, the Smartphone characterised by a complex technology and a lot of functions has become a tool as well as a space for experimenting and exhibiting, a means to transmit and to spread any idea, information or creative work ... It is connected, tactile and responsible for a new kind of proximity and relationship between artists and their public. The artistic practices and artworks in which the Smartphone is used, though highly diverse, nevertheless belong to a consistent corpus, the underlying motivations of which being different from what generally characterises an artwork. The power of Mobile Art lays in its ability to adapt and to transform itself. Imagination is able to continuously extend beyond technology to bring itself within everyone's reach. It is a democratic, desacralized and popular art.

While shopping in a retail store today the customers are often interacting with multiple sale channels when making a purchase. These channels can include in‑store terminals, the customers’ smartphone etc. This thesis looks at how physical mobile interaction can be implemented to enhance the experience when using different channels for a purchase.

This thesis presents the result of a research conducted with the blind and visually impaired in scanning a QR-code and finding medical product information. Three prototypes were developed through Design Science Research Methodology and tested via a talk aloud protocol and observation. Qualitative data was gathered through a semi-structured interview for background of the participants and after each test. The participants came from the Swedish Association of the Visually Impaired in Malmö and consisted of four people. The development of the prototypes was conducted iteratively with the feedback from the tests. The first two prototypes were designed to find navigational and contrast issues and the third prototype, to correct the issues. The result was a solution that effectively met the needs and preferences of the participants as well as the insights to take the information architecture into account when developing, before the design and functionality.

The customer concept becomes more intertwined with the provider of products as serviceoriented business models is offered to the customer. This shift is referred as servitization in which innovation occurs in the company processes by shifting focus from providing products to providing product service systems (PSS). However, the servitization of the manufacturing industry has been slow compared to other sectors and there are many barriers to overcome for the transformation. Use phase data could be used as an enabler to resolve barriers to PSS. The collection of use phase data could be done through the usage of automatic identification technologies like QR codes. Despite the promising opportunities with collection of use phase data there are many challenges. Among them are the identification of use cases for the data. This study therefore aimed to identify both use cases and needed use phase data when collecting data using QR codes.  The manufacturing company Bosch Rexroth AB and their service department were chosen as a case study company, to establish their view on the use cases for QR codes. Additionally, a literature review identified the use phase data need for each use cases derived from the theory. The collected data was analyzed through an explanation building analysis in which plausible and rival explanations to the result was brought up. This resulted in five identified use cases for QR codes and from the use cases one identified need for use phase data. The identified use cases mainly providing value to the provider were derivation of new products or services and improvement of current products or services. The identified use cases mainly providing value to the external customer were the offering of predictive maintenance, the assistance in operations and the creation of a digital passport or image. The identified use phase data need was service data but also additional product related data that does not concern use phase of the products was also needed for the use cases.

Background. As the real estate sector increasingly integrates smart technology, the security of access control systems like QR code-based authentication needs rigorous enhancement. The prevalent use of QR codes in access management presents unique challenges in security and power efficiency, particularly in standalone systems that operate independently of continuous power sources. Objectives. This thesis aims to develop and explore a secure and efficient QR code-based authentication system tailored for real estate. It focuses on improving security measures against potential breaches and optimising power consumption to extend the lifespan of battery-operated devices. Methods. The research employs a mixed-methods approach, beginning with a comprehensive analysis of existing QR code-based systems to identify common vulnerabilities through threat modeling and a literature review. This is followed by the development of a security framework that addresses these vulnerabilities while considering hardware limitations. The performance of the suggested solution is evaluated. Lastly, a Proof of Concept (PoC) is implemented to validate the effectiveness of the proposed solutions under simulated real-world conditions. Results. The study successfully identifies multiple security vulnerabilities in current QR code systems and introduces a security model that mitigates these risks effectively. The implemented PoC demonstrates a improvement in security without compromising the power efficiency of the authentication system. Power consumption measurements indicate a balanced trade-off between system security and operational longevity. Conclusions. The thesis concludes that enhancing QR code-based authentication systems with a security framework can elevate the security level while maintaining efficient power use. This research contributes to the field by providing a scalable model for secure real estate management that can adapt to various operational environments and hardware configurations. / Bakgrund. I takt med att fastighetssektorn integrerar alltmer smart teknik behöver säkerheten för åtkomstkontrollsystem som använder QR-kodbaserad autentisering förbättras. Den utbredda användningen av QR-koder i åtkomsthantering innebär unika utmaningar för säkerhet och effektivitet, särskilt i fristående system som fungerar oberoende av kontinuerliga strömkällor. Syfte. Arbetet syftar till att utveckla och undersöka ett säkert och effektivt QR-kodbaserat autentiseringssystem anpassat för digitala fastigheter. Arbetet fokuserar på att förbättra säkerhetsåtgärder mot potentiella intrång och optimera energiförbrukning för att förlänga livslängden på batteridrivna enheter. Metod. Forskningen använder olika metoder som börjar med en analys av befintliga QR-kodsystem för att identifiera vanliga sårbarheter genom hotmodellering och en litteraturöversikt. Detta följs av utvecklingen av en säkerhetsram som adresserar dessa sårbarheter samtidigt som hårdvarubegränsningar tas i beaktande. Prestandan hos de föreslagna lösningarna utvärderas. Slutligen skapas en Proof of Concept (PoC) för att validera effektiviteten hos de föreslagna lösningarna under simulerade realistiska förhållanden. Resultat. Studien identifierar flera säkerhetssårbarheter i nuvarande QR-kodsystem och introducerar en säkerhetsmodell som minskar dessa risker. Den genomförda PoC:en visar en förbättring i säkerhet utan att kompromissa med energieffektiviteten i autentiseringssystemet. Mätningar av energiförbrukningen indikerar en balanserad avvägning mellan systemets säkerhet och operationell livslängd. Slutsatser. Arbetet drar slutsatsen att förbättring av QR-kodbaserade autentiseringssystem med ett säkerhetsramverk kan höja säkerhetsnivån samtidigt som effektiv energianvändning bibehålls. Denna forskning bidrar till området genom att tillhandahålla en skalbar modell för säker förvaltning av digitala fastigheter som kan anpassas till olika driftsmiljöer och hårdvarukonfigurationer.
