NFC is a world standard since 2004 which is now within every smartphone on the market. Such a standard enables us to do mobile transactions (mobile payment) in a secure way along with many other information- based tap’n play operations. This book has a double role for computer scientists (from bachelor students in CS to IT professionals).

Technological changes have often produced important social changes that translate into spatial and planning practice. Whereas the intelligent city is one of the unavoidable and even dominant concepts, digital uses can influence urban planning in four different directions. These scenarios are represented by a compass composed of a horizontal axis opposing institutional and non-institutional actors, and a second axis with open and closed opposition.

The dominance of trusted intermediaries could be weakened by blockchain, a distributed ledger technology, one of the functions of which is to constitute timestamped proofs by replacing inter-individual trust with algorithmic trust. Blockchain self-executing smart contracts allow us to rethink the practice in the domain of e-commerce, interbank communication, fundraising (and ICOs), justice (timestamping evidence, acts authenticated by blockchain) and businesses in numerous sectors (entertainment, AI, health, real estate, tourism, transport, etc.) which attempt to propose new services by benefiting from blockchains. This book aims to put into perspective the technical innovations and the uses brought about by blockchain, by identifying that which has a medium- or long-term impact, all while taking into account the social, economic, judicial and administrative resistances that are likely to develop.

Geomatics is a field of science that has been intimately intertwined with our daily lives for almost 30 years, to the point where we often forget all the challenges it entails. Who does not have a navigation application on their phone or regularly engage with geolocated data? What is more, in the coming decades, the accumulation of geo-referenced data is expected to increase significantly. This book focuses on the notion of the imperfection of geographic data, an important topic in geomatics. It is essential to be able to define and represent the imperfections that are encountered in geographical data. Ignoring these imperfections can lead to many risks, for example in the use of maps which may be rendered inaccurate. It is, therefore, essential to know how to model and treat the different categories of imperfection. A better awareness of these imperfections will improve the analysis and the use of this type of data.

Digitalization is a long socio-historic process in which all areas of society's activities are reconfigured. In the first volume of Digitalization of Society and Socio-political Issues, there is an examination of the transformations linked to the development of digital platforms and social media which affect cultural and communicational industries. The book also analyzes the formation of Big Data, their algorithmic processing and the societal changes which result from them (social monitoring and control in particular). Through diverse critical reflections, it equally presents different ways that digital participates in relations of power and domination, and contributes to eventual emancipatory practices. Following on, the second volume examines the transformations that are linked to digital practices that affect the production, circulation and consumption of information, as well as new forms that are taken by social mobilizations. It treats several important issues in the digital era that are more likely to become the subject of public debates, among which one can include the renewed relationship between research and digital. Through diverse critical reflections, it equally presents different ways that digital participates in relations of power and domination, and contributes to eventual emancipatory practices.
