THE WORLD’S FIRST BIOMETRIC MONEY: GHANA’S E-ZWICH AND THE CONTEMPORARY INFLUENCE OF SOUTH AFRICAN BIOMETRICS

In January 2008 the Ghanaian Central Bank announced that it had introduced a new centralized mechanism for the settlement of transactions between the Ghanaian banks. This interbank switch, as it was called, was purchased from, and managed by, the South African company Net 1 UEPS, and it had a unique central organizing principle. The switch was indexed biometrically, using a key derived from the ten fingerprints of account holders. This new interbank switch and a smartcard encoded in the same way has equipped Ghana with the world’s first biometric money supply. This article is an effort to explain the development and significance of this biometric money, which Ghanaians call the e-Zwich. It traces the way in which biometric registration in Ghana (as in other African countries) has leaked from the mundane, difficult, and mostly unrewarding, task of civil registration into the more properly remunerated domain of monetary transactions. Viewed in the light of the rich historical anthropology of money in West Africa, what is at stake in Ghana may be much more significant than any of the current participants fully realize. Perhaps the most interesting finding of this study is that the e-Zwich system might actually succeed.
