Gemensam betalningsplatform, med hjälp av blockkedja och öppen bankteknologi (Swedish)
Abstract [en]

There are various large competitors, dominating the digital payment market. These competitors acquire most of the customers, maintaining their dominant influence in the market by charging customers and merchant’s fees for mobile payments. The purpose of this study is to investigate and develop a payment system that connects various payment applications and bank services. This system is developed with the help of blockchain and open banking technology. The blockchain system is utilized as a secure universal database, while the open banking technology is used for transactions. This study proposes an architecture for a multi-sided payment platform. The architecture follows the microservice design pattern which allows the components of the system to be individually developed and maintained. A prototype system was developed as a proof of concept for the architecture, proving the possibility of a multisided payment platform. The “ICA Handla” payment application and Nordea (open banking) system were used to connect to the prototype through gateway programs. The purpose of gateway programs is to connect a mobile payment application or a bank service with the blockchain system. The multi-sided payment application creates opportunities in the digital payment market.

Abstract [sv]

Det finns flera dominerande konkurrenter på den digitala betalningsmarknaden. Dessa företag har en majoritet av kunderna och upprätthåller sitt dominerande inflytande på marknaden genom att ta avgifter från kunder och handlare för mobila betalningar. Syftet med denna studie är att utveckla ett betalningssystem som ansluter olika betalningsapplikationer och banksystem med hjälp av blockkedjeteknik och öppen bankteknologi. Blockkedja-systemet används som en säker universell databas, medan den öppna banktekniken används för transaktioner. Denna studie utvecklade en arkitektur för en gemensam betalningsplattform. Arkitekturen följer ett mikro-tjänst designmönster vilket tillåter systemets komponenter att utvecklas och underhållas individuellt. En prototyp utvecklades som en konceptvalidering för arkitekturen, vilket bevisar möjligheten till en gemensam betalningsplattform. Betalningsapplikationen “ICA Handla” och Nordea öppen bankteknologi är anslutna till prototypsystemet via ett gateway program. Syftet med gateway programmet är att ansluta mobila betalningsapplikationer eller banktjänster med en blockkedja-system. Den gemensamma betalningsapplikationer skapar möjligheter på den digitala betalningsmarknaden.
