Identity theft is a very big concern all over the world these days. Quite a lot of people are exposing themselves to identity theft when they make online transactions.  As a result, many people and companies have turned to  Biometrics  as a way of facilitating all sorts of online commerce. Biometrics signatures like fingerprints and iris scans for instance,  are quite difficult and are in many cases practically impossible to fake consistently, making them the obvious choice for online authentication in online transactions in a great deal of many cases. Biometrics technology is clearly going to figure quite a bit in many future online transactions and money transfers.
