Theorizing Biometrics, Identification and Digital Payment

Logo 4S Toronto 2026: Technopower

In 2001, Phil Agre famously argued that “Your Face Is Not a Barcode.” Yet, biometric identification and digital payment have seemingly become co-constitutive since then. After their integration into payment infrastructures, fingerprinting, face recognition, and iris scans have been adopted unevenly. Nevertheless, they already play a significant role in the everyday usage of digital monies around the world. Consequently, mobile media devices have become key mediators of what is termed a “repersonalization of money.” Smartphones and smartwatches now serve both as ‘contactless’ payment gadgets and mobile media, integrating former infrastructures such as payment cards (Giessmann 2026) and the mobile phones’ humble SIM cards into appified wallets.

In my 4S contribution, I aim to theorize the contemporary relationship between biometrics and 21st century digital payment technologies in a historically grounded way. In networked accounting, every non-cash payment transaction depends on a threefold relation of identification between accounts, bodies and personhood. But what has driven, and continues to drive this identificatory imperative to fuse an account, a body, and a person? How does this methodological individualism of ‘capturing the economic subject’ relate to a political economy of identification? “[W]e mobilize empirical materials so as to make a set of theoretical points,” wrote Marianne de Laet and Annemarie Mol (2000: 255). In my talk, I will follow their methodological advice, and draw on Western- und non-Western examples symmetrically.

Materiality of Cooperation

Cover Materiality of Cooperation
 
The volume investigates the socio-material dimension and media practices of cooperation – before, during and beyond situations. Cooperation is understood as reciprocal interplay operating with or without consensus, in co-presence or absence of the involved actors in distributed situations. Artefacts, bodies, texts and infrastructures are the media that make cooperation possible. They enable and configure reciprocal accomplishments – and are themselves created through media practices in cooperative situations.

The Practice Turn in Media Studies

Cover Connect and Divide The Practice Turn in Media Studies

 

“Connect and Divide” took a long time to be published, but now the book is finally here. Bringing practice theory/praxeology and media studies together seems like an endeavour that needs time for deliberation. My own contribution “How to Coordinate Digital Accounting? Infrastructuring Payment and Credit with the Eurocard” is a business history from the lost 1970s/1980s social world of an European credit card called the Eurocard. It focuses on practices of coordination, and combines these with a framework of thinking about practices of delegation, and registration/identification.

Within the volume’s long production time, the reproduction of images somehow took a strange trajectory. This is why I republish them in this blog post for your viewing and reading pleasure. And do not forget to check out the other excellent contributations to this publication of the German Research Foundation’s third Media Studies symposium! It is also the first time that this has been a transatlantic event. I am very grateful to have been a part of it. „The Practice Turn in Media Studies“ weiterlesen
