Elections have emerged as a leading area for the application of biometric technology in developing countries, despite its high costs and uncertainty over its effectiveness. This paper finds that a reduction in the probability of post-election violence by only a few percentage points could offset the cost of the technology. However, this is possible only in particular situations.
This paper surveys 160 cases where biometric identification has been used for economic, political, and social purposes in developing countries. One primary conclusion is that identification should be considered as a component of development policy, rather than being seen as just a cost on a program-by-program basis.
