As part of the OPTIMOS 2.0 funding project of the German Federal Ministry for Economic Affairs and Energy (BMWi), a partner develops the TicketIssuance app for secure hardware-based storage of high-priced tickets. The app has implemented a previously unknown technology using the Secure Element and the NFC interface. It is therefore imperative to in...
With the increasing spread of digital services and apps, the risk and damage potential of attacks and identity theft increases. In addition, there are services, such as season tickets on public transport, that must be protected at a high level of security so that there is no significant risk of abuse. The OPTIMOS 2.0 Project wants to establish an o...
Worldwide, strongly increasing trends towards the use of mobile services can be seen in almost all areas of society, economy and administration. A secure eID service is the user’s key to mobile online services. Many branches are recognizing this. The research project OPTIMOS 2.0 develops an open SE-based ecosystem for mobile services. This supports...
In frame of OPTIMOS project (Open, Practical Infrastructures for Mobile Services) an open practical ecosystem based on Near Field Communication (NFC) will be developed and demonstrated by different implemented use cases in the field of public transport services in two German regions. One of the main objects is e-ticketing. For the generic definitio...
The comprehensive digitalization of the economy requires efficient actions from all market partners involved. This also applies to public transport sector.

... In early work, Mallat et al. [24] investigated adoption of SMS-based mobile ticketing in public transportation. More recent studies focused on alternative ticketing approaches, including a study carried out by Stopka et al. [33] on an NFCbased open ecosystem to offer secure identification for mobile ticketing services in the domain of public transportation. A key finding were practical issues regarding the interoperability of current mobile devices. ...
... We consolidated the main advantages, disadvantages and challenges related to journey maps and personas mentioned by the primary study authors, as presented in Table 1. Considering the context provided by the application of DT, journey map and personas techniques, Schäfer et al. [51], Dantas et al. [14] and Souza et al. [8] provided some models, methods and tools for this purpose. Schäfer et al. [51] (E5) presented the Development of a Concept for Evaluation User Acceptance and Requirements for the E-ticketing in Public Transport system using the techniques personas, scenarios and journey maps. ...
