Master Thesis: Determinants and Success Factors that Influence the User Adoption of Mobile Payments in Germany

Adeteju Enunwa recently submitted and successfully presented her Master thesis about the determinants and success factors that influence user adoption of mobile payments in Germany. We asked her to provide a short summary of her thesis for our blog:


Determinants & Success Factors that Influence the User Adoption of Mobile Payments in Germany

By Adeteju Enunwa

Research Model inspired by the “Unified Theory of Acceptance and Use of Technology” (UTUAT) model by Venkatesh et al. [1] and “Diffusion of Innovations” Theory by Rogers [2].

The swift adoption of smart phones globally has impacted various industries, thus  resulting in an explosion of mobile applications being used for the execution of various tasks across all sectors of the economy. The emergence of financial technology firms (Fintechs) who have redefined banking and payment has also resulted in an evolution in the way proximity based payments are made, with a gradual shift from cash, to contact only cards, to Dual Interface (DI) cards which supports contactless payments and now to mobile payments. Although, the payment scene has welcomed the presence of additional stakeholders such as Mobile Network Operators (MNOs) and Smart phone manufacturers e.g. Apple, Samsung with the evolution in NFC payments, mobile payments remains at a stagnant level with little or no growth in the adoption rate in Germany when compared to other European countries such as France, United Kingdom, Spain etc. where contactless is gradually the new alternative to cash.

The conceptual model was tested using two qualitative research methods namely: Observation and Interviews to carry out the study. The Observation phase was carried out over a period of five (5) days at a canteen in Munich, whereby the mode of payments of an average of one hundred and twenty (120) people were observed daily. Afterwhich, interviews were conducted to enable the researcher ascertain the factors that influence the intention to use and adopt mobile payments.

During the study, it was revealed that Data Privacy and Security were the core factors that would influence the intension to use mobile payments. Interestingly cost was an additional factor that also impacted the user’s perception on usefulnesses which was derived by comparing the value added offerings and associated cost to existing alternatives.

Due to the sample size, there were some limitations based on the location and the fact that most participants interviewed were male, thereby social factors such as the influence of gender could not be explored. However, two core external factors beyond the control of the end user were identified as the major challenges facing the adoption of mobile payments in Germany. (1) The inexistent support and specification standards for mobile payments by the domestic network known as girocard and (2) the poor acceptance by merchants. A strategic collaboration among stakeholders of the payment industry will be required if mobile payments is to be successful in Germany. The average end user must be confident enough to visit any merchant without the fear of limited acceptance for contactless payments

Getting your Master of Science without quitting your job!

Did you ever think about getting back to University to earn your Master of Science? Lifelong learning is essential, especially in a world that is constantly changing. Then some questions might come up: But what about my job? Where would I live and how would I be able to pay for this? Okay, there may be some online programmes, but a) how credible are these and b) would I really be motivated to learn all this on my own as self-study?

Web Science at TH Köln

We designed our Master programme in Web Science so that you would neither have to quit your job nor have to move. It is designed for students, who work full-time and want to pursue their Master of Science degree in part-time.

2 on-site weekends in Cologne, combined with eLearning and interactive online sessions

Web Science Master programme combines on-site and online sessions

To make this feasible, the programme is mainly held online, but we start and end each semester with an on-site weekend. During the first weekend, lectures are held and project teams are formed. And as we heard, the students meet in the evenings and exchange experiences and get to know each other. This is also very important as during the semester most of the students will mainly meet online when working together in their projects.

During the semester, every Tuesday and Thursday online sessions for the courses are held in the evenings (19.00 – 22.00 o’clock). Often the students have to prepare some small exercises in advance, read specific literature, or watch online lectures. In that way, the online sessions can be highly interactive, where students e.g. work together in smaller groups on a given task, which is then discussed in class together with the lecturer. This makes it possible for students to apply directly what they learned, engage in discussions (which also supports deeper understanding), and get immediate feedback. In modules which include a project these online sessions are also used to discuss the progress, challenges and opportunities of the project. Individual feedback is very important, so that the students can improve their project constantly throughout the semester. Interactive sessions, working together in groups, engaging in discussions and receiving individual feedback is something that differentiates the Web Science Programme from others online programmes in which students mainly have to study on their own. Self-study may not be that motivating and when there is increased stress at work, it may be very tempting to postpone it. Like the membership in the gym, where you for sure start practicing again next week 😉 . We can see that the students in our programme are highly motivated, work really well together, and help each other.

During the last weekend in each semester, the second on-site meeting is held. Here, the students will have their exams, which can be a written exam or a project presentation. It is always exciting; not only due to the exams, but also to see the final results of the often very interesting projects.

Answering the questions

So what about the “But, …” questions mentioned at the beginning? I think we addressed these in our programme:

  • But what about my job? Where would I live and how would I be able to pay for this?

You can keep your job and thus won’t loose your income. You wouldn’t have to move, because we only have two on-site weekends per semester, so for most students it is feasible to travel for those weekends to Cologne.

  • Online programmes: How credible are these? 

Our programme has be examined by the independent and professional agency AQAS. The accreditation of our Web Science Master programme has been successfully renewed until 2023.

  • Would I really be motivated to learn all this on my own as self-study?

Although you may have to work on some exercises or read literature on your own, you mostly have meetings together with peers or work in teams, which makes it easier to focus and to stay motivated.

So, what are you waiting for? Apply now 🙂

New publication by Christian Klemm and Wolter Pieters

Christian Klemm published together with Dr. Wolter Pieters an article in Ethics and Information Technology. The article “Game mechanics and technological mediation: an ethical perspective on the effects of MMORPG’s” argues that discussions around video games should not only include the effect of their content (e.g. violence) but should also consider the effects of game mechanics. They analyzed ethical dimensions of behavioral game design and conclude with proposals for a better design. The paper is published as Open Access and is available here.

Christian Klemm graduaded in our Web Science programme in 2016. Dr. Wolter Pieters is assistant professor at TU Delft and was a lecturerer in Computer Ethics in our programme until 2015.
