While most of us, if we live in a representative democracy, think about election day as happening every so often. Other people are always thinking about elections, not from a partisan or even a political perspective but from the technical and scientific aspects of how to engineer better electoral mechanisms.
The E-Lected blog is the work of one group of people answering the description above. They do good work. Check them out by clicking their logo below.
Today they have a timely contribution: Technological solutions to the problems of voter authentication. The closing paragraph is quoted below but it's well worth reading the whole thing, and if you're interested in nuts-and-bolts electoral issues, e-lected is worth a regular visit.
As a blog advocating for the implementation of the electronic technologies to strengthen modern democracies, we are convinced that, if a polling station has a reliable electronic poll book with a robust database which includes biographic and biometric information of every eligible voter in, and the voters are authenticated by means of a fingerprint-based biometric device, both problems can be solved and election integrity and legitimacy guaranteed.
