This book offers an in-depth investigation into the digitisation processes of Europe’s border regime. It shows how sociotechnical imaginations of future borders drive forward the expansion of databases in the European governance of mobility. With a focus on the European Union Agency eu-LISA, one of the most significant and rapidly advancing actors in the digital border regime, the book serves as a gateway to understanding the key agents, visions, technologies and practices at work. Asking broader questions about exclusion, discrimination, violence and mobility rights, this is an original contribution to our understanding of future borders in Europe.
