We are interested in sales of fingerprint sensors to government
entities for use in airports, physical access to government
facilities, immigration control, and logical access to computers.  We
are not interested in AFIS applications and we are not interested in
10 finger systems. 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.

Some applicable companies include: Digital Persona, ST
Microelectronics, Identix, and Crossmatch. Their technologies might be
optical (likely) or capacitive.  The measurement might be made on the
full finger (likely) or it might be a swipe measurement.

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