Mobile Commerce has gained increasing acceptance amongst various sections of the society in previous years. The reasons for its growth can be traced back to technological and demographical developments that have influenced many aspects of the socio-cultural behaviour in today’s world. The need (and/or wish) for mobility seems to be the driving force behind Mobile Commerce. The launch of UMTS technology has provided Mobile Commerce with the necessary verve. Mobile Financial Services build a cornerstone of Mobile Commerce. They comprise of Mobile Payment and Mobile Banking. Mobile Banking, the primary research object of this study, in turn consists of the following sub-applications: 1. Mobile Accounting 2. Mobile Brokerage 3. Mobile Financial Information Mobile Financial Information can be considered as an independent module and offered as a stand-alone application. Each of the first two subapplications is offered, in contrast, invariably in combination with information services. An empirical survey of the customer acceptance conducted under the ambit of this study reveals large-scale interest in Mobile Banking. The customer interest and the willingness to pay however vary for individual services. It is therefore necessary to design offers taking cognizance of the needs and wishes of relevant target groups. Mobile Banking presents an opportunity for banks to retain their existing, technology-savvy customer base by offering value-added, innovative services and to attract new customers from corresponding sections of the society. The customer survey provides evidence that such sections in the meanwhile include the affluent and financially relevant groups of the society in Germany. The time seems to be ripe to convert this non-negligible customer interest into business-driving customer demand. A proactive attitude on the part of the banks therefore seems to be recommendable. Many banks in Germany have come to regard Mobile Banking as a necessary tool for thwarting negative differentiation vis-à-vis rivals and to foster/retain an innovative image. This self-reinforcing dynamism is expected to gain currency in near-future so that Mobile Banking services could soon advance to a standard product – on the lines of Online Banking – offered by more or less each and every bank.
