With the upcoming of ubiquitous computing, banks and financial institutes meet new chances and challenges in their business. The goal of this paper is to identify requirements and test technologies for ubiquitous payment (u-payment). The work was done in a joint research project of our research team and United Bank of Switzerland (UBS). To derive the results the project team conducted interdisciplinary innovation workshops, built demonstrators and analyzed user and UBS experi-ences. The paper first evaluates the key features of u-payment in comparison to mobile payment (m-payment). Then, it describes the Preferred Payment Architecture (PPA), which is developed by Mobey Forum, a global, financial-industry driven forum. UBS is one of the founders of the forum and presses ahead with this architecture as this recommendation implements the requirements of customers, financial institutes and merchants in equal measure. The research team developed the test platform BluePay, which implements some chosen requirements of PPA in order to gain experiences with local payments in a store with the technologies Bluetooth and Radio Frequency Identification (RFID). The main results of this work are a definition of u-payment by the authors as unobtrusive, ubiquitous, invisible, and in the environment integrated payment, an evaluation of technologies and requirements of the u-payment system demonstrators, and some implications for the adoption path from m-payment to upayment.
