Research Objective and Scope

The primary objective of this dissertation is to determine whether payment systems utilizing fingerprint technology possess the potential to either supplement or replace traditional payment methods in the future. By conducting a detailed case study of the "digiPROOF" system implemented at EDEKA, the research investigates user acceptance, technical performance, and strategic viability, aiming to provide a holistic assessment of biometric payment systems in real-world retail environments.

• Analysis of success factors for payment systems (cost, convenience, security, privacy).
• Evaluation of the digiPROOF system from both merchant and customer perspectives.
• Empirical survey data comparing user and non-user attitudes toward biometric payments.
• Assessment of current trends in electronic and mobile payment systems.
• Comparison of digiPROOF against traditional payment methods like cash, credit, and debit cards.

Excerpt from the Book

Summary of Chapters

Frequently Asked Questions

What is the core focus of this dissertation?

The work investigates the future prospects of payment systems based on fingerprint technology, specifically analyzing whether they can successfully supplement or replace established traditional payment methods.

What are the primary themes discussed in the research?

The research centers on identifying critical success factors for payment systems, such as cost-efficiency, user convenience, technical security, and consumer privacy, while exploring the integration of biometric solutions in retail.

What is the ultimate research objective?

The main goal is to evaluate if digiPROOF, a fingerprint-based payment solution, meets the necessary success criteria to gain a critical mass of users and achieve long-term market sustainability.

Which scientific methodology was utilized?

The study employs a qualitative case study methodology, triangulating data from interviews with stakeholders (merchant and provider) and quantitative/qualitative surveys among system users and non-users.

What topics are covered in the main body of the work?

The main body covers the theoretical history and classification of payments, a detailed technical and strategic overview of digiPROOF, and an empirical survey analysis assessing its performance in real-world retail.

Which keywords best characterize this academic work?

Key terms include Payment Systems, Biometrics, Fingerprint Recognition, User Acceptance, Convenience, Security, Privacy, and Retail Technology.

What are the most frequent reasons given by non-users for not registering with digiPROOF?

The most common reasons are a strong preference for cash due to better expenditure control, general data protection or security concerns, and the perception that existing payment methods are already sufficient.

How does digiPROOF handle the security of biometric templates?

The system uses an encrypted hash algorithm to store reference points of fingerprints, ensuring that the original image cannot be reconstructed from the stored data.

What is the main advantage of digiPROOF from the merchant's perspective?

Merchants benefit from a more efficient, lower-cost payment process compared to traditional credit/debit systems, better management of return debit notes, and increased customer retention.
