[M  =  Manager; B  = Bob]
M:  Hi, Bob. Welcome back. So, how are you getting on?
B:  I' ve  made some progress since we last spoke.
M:  So, what systems have you  come up with?
B:  I'v e looked into four of the identification technologies that you suggested last month.
M:  And?
B:  As we thought, we need to  look at biometrics in order to obtain the fastest and most secure system.
M:  And what types of biometrics did you look at?
B:  Well, biometrics covers the  physical measurement of a person - their  voice, their fingers,  the shape of their face, or the patterns of their irises.  And the most promising technology is iris scanning.
M:  Really? What about that other system that we spoke about - capacitive scanning? Have you looked  into that?
B:  Yes, I’ll come to that in a  moment.
M:  Remind me why biometrics is  going to be the best solution.
B:  Well, take the human iris.  For a start, every human iris  is  individual . The chances of two different irises being the same are one in  ten to the power of 180.
M:  I follow  .
B:  And the iris structure doesn't change during a  person's lifetime. Basically, you will have the same iris structure when you are old that you had as a one-year-old baby. Unless of course you have to have eye surgery. That might change the iris structure.
M:  So  iris scanning, then.
B:  In fact, the basic iris  recognition technology is  known as 'image capturing', not scanning.
M:  What's the difference?
B:  Tmage capturing is video; scanning is, well, scanning.
M:  Yes, I see what you mean.
B:  With image capturing, there's  no physical contact, unlike fingerprint scanning or capacitive scanning. So no germs or bacteria are transferred.
M:  Go on, tell  me more.
B:  It's accurate. And it's  much more reliable than voice recognition. And we agreed that accuracy is  our first  priority.
M:  Agreed. Any other good points you discovered?
B:  It's flexible.  If you want, you can combine iris scanning with other  systems, like PIN  numbers or swipe cards. Or you can use iris scanning as a  stand-alone system .
M:  So how does the system  operate?
B:  In stage  1, the registration stage, you capture an image of the person's iris.  Next, you upload all  the details of the images plus the person's ID onto the computer. Then, for identification, when the person gets to the access gate, they face the iris scanner, and the computer matches the
image of their iris with the details on the database.
M:  And how long does all that take?
B:  Less than two seconds.
M:  I'm impressed! Anything else?
B:  Yes,  scalability. Once you have the system up and running, you  can add thousands of people to the database. It has no effect on accuracy or access time at the gate.
M:  So you're saying the system could handle thousands of people.
B:  You can have a multi-million person database! This system is going to be huge , I can tell you!
M:  Good. Oh!  I must go. I'll catch up with you after the weekend.
