Machine readable passport

This is an interesting topic. In its high tech quest for fraud prevention, Britain for instance has been developing an e-Passport which will contain a micro-chip encoded with information about the bearer's facial biometrics . Facial recognition will map various features on the face, for example, the distances between eyes, nose, mouth and ears. The measurements will be digitally coded and held on an electronic chip secured in the passport page. The technology is suitable for border control checking. It enables immigration officers to produce an image of the passport holder for checking the authenticity of the document against the person.

As a technology enthusiast, a consumer and a traveller, I wonder when we will begin to see humans being tagged with RF-IDs that are embedded in our bodies; this way we will do away with credit cards, passports and other identification documents. It sounds scary to think that authorities will be able to trace our whereabouts, our habits and all pertinent information about us just by scanning us in a fraction of a second just like a bar coded merchandise!!
