I found the latest biometric scanner to be finger vein scanners. The authentication is quick, non-invasive means of making sure people really are who they claim to be. Where i always a problem....but now I am happy with it so much that a big burden from my head has been deleted. This new biometric security is that big daddy of all biometric scanners. I recommend everyone concerned with safety and security measures should try it out. The one I use is from a company in Atlanta USA called M2SYS Technology. The finger vein reader captures images of the vein patterns inside your finger. These, like other biometric patters are unique. In addition, because they are inside your body, finger vein patterns are virtually impossible to replicate.
