The digital transformation of companies is driven by trends, and banks are no exception. In retail banking, online banking has become indispensable. Against this background, M-PESA stands out. M-PESA is a mobile money service provider of the Kenyan mobile communications company Safaricom. To use M-PESA, a cell phone and a SIM card are required. After registration, money can be deposited, withdrawn and transferred to other users. In contrast, the Austrian payment service ZOIN links the private bank account with a cell phone number. After activation, only the cell phone number of the recipient has to be entered instead of the IBAN. Based on these examples, the reasons for rejection and acceptance of digital banking applications were investigated.
A qualitative research approach using guided interviews was selected for this purpose. Nine interviews were conducted and evaluated using an approach originated by Mayring. The results show that security plays the biggest role and is decisive for the acceptance of a new digital banking application. Other factors are user-friendliness, speed and personal recommendations.
