This open access book explores how biometric data is increasingly flowing across borders in
order to limit control and contain the mobility of selected people namely criminalized
populations. It introduces the concept of bio-bordering using it to capture reverse patterns
of bordering and ordering practices linked to transnational biometric data exchange regimes.
The concept is useful to reconstruct how the territorial foundations of national state autonomy
are partially reclaimed and at the same time partially purposefully suspended. The book
focuses on the Prüm system which facilitates the mandatory exchange of forensic DNA data
amongst EU Member States. The Prüm system is an underexplored phenomenon representing diverse
instances of bio-bordering and providing a complex picture of the hidden (dis)integration of
Europe. Particular legal scientific technical and political dimensions related to the
governance and uses of biometric technologies in Germany the Netherlands Poland Portugal and
the United Kingdom are specifically explored to demonstrate both similar and distinct patterns.
