No longer are forms needed to printed, taken out and then taken away and kept securely.
People will no longer be able to enter the site under false pretences (as it has been done in some cases by activists or reporters with hidden cameras). Each visitor will be verified upon BioSentry registration.
As an example, a Rational engineer who one day may be doing an installation in a country and area where over the following couple of days suffers from an outbreak of Avian Flu, will be alerted of the fact and if he tries to sign in to a site in a different country or area, the site management will be alerted immediately. This can save the industry significant amounts of money as well as embarrassment.
