“…It is also the case that the link between bureaucratic objects or ‘things’, issued to be worn or carried by illegalised migrants (wristbands and bureaucratic papers), and the data systems that gather and share their biometric information has not been developed. Research on documentation issued to illegalised migrants as they go through the process of registration, submission of asylum applications, interviews, reviews of decisions taken on their status has focused on legal-bureaucratic papers within the broader perspective of technologies of governance (Bigo, 2008; Bloch et al, 2014; Dean, 2010; Mountz, 2011; Tazzioli, 2014) or papered governmentality (Abarca and Coutin, 2018; Salmenkari and Aldarwoodi, 2023). As my primary concern is to consider and examine the materiality of technological infrastructures and their importance in constructing the migrant body within relations of power, I will draw insights from work in critical security studies and in particular feminist perspectives for a broader conceptualization of the ways in which data systems are forming and (re)forming the migrant body.…”
