During recent decades, satellite systems and digital technology, the Internet included, gradually have begun to meet and become recombined with existing practices of banking. Homebanking, internet-banking, e-codes, cashpoints, debit cards, card readers in the home and other places, are perhaps some of the most visible expressions of such recombinations. By allowing new forms of organization and interaction, the marriage between banking, satellite and digital techniques has involved radical changes for banking activities as well as for  the individual and society at large. At the same time, it involves a number of dimensions and problems increasingly discussed in terms of crime, threats, uncertainties and risks deriving from particular innovative practices of recombination called, for instance, skimming, hacking and Trojan attacks. In this paper, I explore an issue which hitherto has been little investigated: what do banks do in practice when they deal with problems, threats and uncertainties related to such ’unwanted’ innovative activities? Here I concentrate on Nordea AB, a Stockholm-based financial services group operating in Northern Europe, which is described as ’the world leader of internet banking in terms of usage, having more than 5.9 million online customers doing more than 260 million payments/ year” (Wikipedia). By making more visible the work on security & authentication carried out by Nordea, I hope to illuminate, nuance and problematize more general imaginations of how technologies associated with the Internet can be used in attempts to enact, expand, destabilize or sabotage particular interactions and relations.
