Finally got around to catching up on links I saved during the week that looked like they were worth a second look. Government Computer News (GCN) ran an article back on the 6th of February titled "Biometrics look ready for prime time". I don't have much to say about the title itself as there are many considerations involved in making such a statement that aren't covered in the article, but I can say that the article itself is a useful location marker on the journey. By that I mean that it does a good job of showing what the state of COTS (Commercial Off The Shelf) products is today as the market for biometric products develops.
GCN evaluated a selection of products and gives a summary of their pros, cons, features, performance, value and even prices. The limited set of products chosen for review ranged from eye scanners to fingerprint-enabled thumbdrives, so it lightly covers the gamut available.
