Mobile technology became one of the most vibrant and stimulating areas driving forward the ICT society of the 21st century. Mobile communication networks have evolved into the new delivery platform and services consumption models for many industries and government organizations worldwide. Mobile devices, such as smart phones or tablets, open the door to a great assortment of new applications and services. This may also include new types of specific application settings such as medical environments, support for disabled people, industrial workspaces, process monitoring, automatics and diagnostics or measurement activities in remote and distributed environments. Location, other context information and personal data are used to tailor services directly to the needs of the user. This leads to pervasive environments in which users can always access the Internet. While this seems to be an exciting development it also raises substantial security and privacy concerns which need to be properly addressed. Mobile Commerce (M-Commerce) comprises applications and services that are accessible from Internet-enabled mobile devices. It involves new technologies, services, and business models. Whilst it is different from traditional e-Commerce it can also be considered as an extension of it since, among other reasons, it makes e-Commerce available, in a modern way, to new application areas and to a new set of customers. The goal of TAMoCo is to bring together researchers and practitioners that work in different aspects of mobile communications and services in the context of business and industrial applications. This includes the incorporation of web services and cloud-based services, autonomic mobile computing, and the integration and interplay with urban systems, industrial settings, medical environments and other contexts. Research contributions in application areas such as mobile learning, human centered design, support of disabled people, ubiquitous computing and extended enterprise are also welcome in TAMoco’14. Finally, security is perhaps the most important factor for the success of mobile communications, commerce and mobile applications.
