This essay provides a terminological trajectory of border-related concepts. First, a theoretical development from state-centric to deterritorialized understandings of the border is sketched out, before the methodological implications of a move from descriptions of borders as static entities to investigations of contingent practices of bordering are investigated. Borders as focal points of state power emerge as dispersed and operative across various registers and dimensions from international relations to the mundane sphere of everyday life. Bringing together such a widened understanding of bordering with a mapping of new technologies for the tracking, tracing and profiling of populations the essay develops the twin concept of iBorder/iBordering to draw attention to the constitutive effects of bordering as a contemporary cultural technique of in/exclusion.
