Internationally most Internet trade related payments are performed with the use of a credit card based payment system on the Internet. Payment against invoice is still most common when trading over the Internet in Sweden. The security development, comfort and timesaving indicate that credit card based payment systems on the Internet soon will have a breakthrough in Sweden as well. The Swedish legislation concerning payment is neither especially extensive nor suited to electronic payments but to payments performed with notes and coins. When the legal effects, of a payment performed with a credit card based payment system on the Internet, set in is not fixed.

As a consumer, you can use cards for payment more or less everywhere you go, however, it is not certain that the card can be used for all purchases. When a customer pays with card there arises a card transaction fee charged to the merchant. This is a big problem for businesses where transactions with small amounts are a large portion of sales. An observation at the beginning of this study showed that seemingly similar merchants have chosen to solve this problem in different ways. Some merchant?s refuses card purchases below a certain amount, while others accept card with any purchase.

This thesis concerns the Swedish credit card market to a younger public and specifically Nordea as a card editor. The purpose is to investigate whether a Swedish bank can, and want to build long term relationships with a young public through credit cards, and if so, how they do this.The theoretical background formulated by researchers Bendapundi and Berry consists of four key factors of relationship maintenance; trust, dependency, dedication and constraint. These key factors are also assembled in an analytical framework. The empirical findings mainly consist of interviews with three employees at Nordea. They describe a recent segmentation of the bank?s customers with the issuing of a new credit card; Mastercard Silver.

Aim: Banks? settlement of handling cash and the technological developments of our payment services, leaves us guessing at the outlooks of consumers? payment systems. One of the new payment options arising from this development is mobile payment. With access to internet, mobile payment can take over the role as the primary method of payment, as it can be used on any occasion. Questions are raised about which factors that are affecting the future users? attitude to use mobile payment, and if the service can be a threat to the traditional Card payments.Method: This study is based on a quantitative method by the means of a survey design.

Physical exercise is a trend that continues to grow, especially at the gym, but there are still members that do not use their training card in full. The overall aim of this study was therefore to investigate infrequent member?s experience of their training card. To answer this, focus was on motives to card purchase and perceived opportunities and difficulties of using the training card. The data was collected at IKSU trough a group interview with four managers within the organization, a questionnaire replied by 39 infrequent members and of those 11 individual interviews.

The purpose of this study is to investigate a loyalty card and its relation to accompanying promotional benefits, and their linkages to grocery retail service loyalty. Also, the aim sets out to find relationships between demographic variables and proneness towards the promotional benefits, the loyalty card, and loyalty. A quantitative approach has been assumed and empirical data has been collected through the use of questionnaires. The data has been analyzed through descriptive statistics, correlations, and regression analysis. An operationalization used to measure satisfaction of the loyalty card and attitudinal loyalty is also presented.

Today you can pay in many different ways. You can for instance use cash, credit cards, internet and now even with your mobile phone. Today we can also see new types of technical payment solutions being developed, such as Near Field Communication (NFC), mobile banking or through the use of QR-codes. We have today many different payment methods; therefore it?s interesting to see which payment method people prefer the most.

The purpose of this essay is to elucidate if there is a liability to damages for cardholders, in case of unauthorized use of bankcards, in the event a liability for payment, according to 34 § the Swedish Law concerning Consumer Credits, should not be established between card issuer and cardholder. The purpose is also to elucidate if card issuing companies, in the event a liability for payment is established between card issuer and cardholder, have any possibility to get a larger sum than is allowed by 34 § the Swedish Law concerning Consumer Credits, by demanding damages from the cardholder. Finally there is a judgement of how a court could do if it wanted to hold a cardholder liable to damages because of unauthorized use of bankcards..

In the electronic industrials, power control of AC motors is commonly used. For example power control of a washing machine motor, a vacuum cleaner motor or a coffee machine motor. The company Rejlers Ingenjörer AB has many projects where power control of AC motors is included. A prototype card for this task can save time and money for the company in the future and this is the reason for this thesis.The motors are power controlled by a TRIAC and control of the trigging pulses to the TRIAC. This card is modularly built and can easily be adapted for future projects where the power control of AC motors are included.The prototype card can be used as a subsystem in a larger electronics projects or as it is in lab environment for testing and evaluating new motors..

A majority of the payments that are carried out today are executed through the electronic payment systems. Payments that are executed through these systems are administrated by payment service providers, these providers are, in general, banks. In spite of the socio-economic importance of payments and payment intermediation, there is an uncertainty regarding the legal status of payments and payment intermediation. Some describe payment intermediation as transport of means of payments, while some describe it in terms of claims and intermediation of information. There is, in other words, a need for clarification.

Softube has developed DSP-card and software for simulation of the sound of old tube amplifiers. The purpose with this thesis is to design a compact amplifier with high power to function together with the DSP-card and build a unit that can replace several other guitar amplifiers. The advantages with that kind of solution could be that it would be cheaper, easier to carry and easier to stor than the real amplifiers. The amplifier that has been designed is of class D type with digital PWM modulator. There is several types of amplifier modules on the market that use analog input signal, but if one of them would be used a D-A converter is needed on the DSP card.

Typically, when Faurecia in Torsås are planning a new assembly line, one of the steps is to build a full-scale model of the line in card board, a form of mock-up planning. Faurecia has shown interest in finding an alternative methodology. The purpose was to explore the possibility of replacing today's cardboard based mock-up planning with models in a digital simulation environment.The purpose of the thesis has been to answer some of these complex questions; What are the benefits of using a simulation tool? In what way can we use it? If we choose to use a simulation tool, in what way does it affect our way of planning an assembly line? What are the advantages and disadvantages? Are there any economical and social aspects?Our results made us realize that a digital simulation tool does not replace the card board. On the other hand simulation could be used as a complement.

GPGPU is a collective term for research involving general computation on graphics cards. A modern graphics card typically provides more than ten times the computational power of an ordinary PC processor. This is a result of the high demands for speed and image quality in computer games.This thesis investigates the possibility of exploiting this computational power for image processing purposes. Three well known methods where implemented on a graphics card: FFT (Fast Fourier Transform), KLT (Kanade Lucas Tomasi point tracking) and the generation of scale pyramids. All algorithms where successfully implemented and they are tree to ten times faster than correspondning optimized CPU implementation..

This essay is a product of our examination work on candidate level in Interaction Design. The aim in this project was to design a digital wallet integrated into a cellular phone and make it as an electronic payment tool. In our project the goal has been to create a digital wallet not just for payment, but also develop it into a complete digital wallet, replacing visa, membership card, student cards, id card and receipt. Our ambition is to take care of current qualities of today's wallet and improve where it is possible so that can be replaceable with the digital wallet..

Business and organizations use computer network in a greater extension than ever before, especially for business-critical use. That increase the demand of security for all systems, both against internal and external threats. The demand on the authentication method used today increases. Today they normally uses password or some kind of smart card. I will performa literature study that will investigate the possibility to increase the security in authentication of users without the use of extra hardware.
