Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

This dissertation aims to analyze the potential for fingerprint-based payment systems to become established in the market. It focuses on the digiPROOF system, a fingerprint-based payment solution implemented by EDEKA, a German supermarket chain. The research evaluates digiPROOF based on a framework of success factors for payment systems and analyzes user feedback through a survey.

• The development and history of payment systems
• Success factors for payment systems (cost, convenience, security, privacy)
• Evaluation of the digiPROOF system
• User perception of fingerprint-based payment systems
• The potential for fingerprint-based payment systems to become established in the market
