We are interested in sales of fingerprint sensors to commercial,
non-government entities.  We are interested in several categories of
commerical sales: portable wireless (ex. cell phone and PDA), logical
access to computers, time and attendance, and building access. By
sales, we mean number of units sold (annual unit volume) and sales in
dollars (annual dollar volume sold either for the actual sensor or for
the product into which the sensor was incorporated). We would like
this information by company for 2003 (if available), 2002, and 2001.

Applicable companies include: Sagem, NEC, Cogent, and Printrak.  Their
technologies might be optical, capacitive, or RF. The measurement
might be made on the full finger or it might be a swipe measurement.

The information would be most useful organized in the following way:
1. Company
   a. technology (optical, capacitive, RF)
      i. ergonomic (full finger, swipe)
         1. sales by year
