Welcome to Windows for Tektronics! (You should feel lucky they haven't upgraded to Vista......shudder)

I disagree. I have my Blackberry 8110 provisioned with BIS/BES and swapping the SIM to a candy-bar style phone still allows data usage. Perhaps this is something different with the MUCH newer models? And I can't vouch for BES support as I don't have another device that would use BES with a SIM card. Perhaps this just a function of my carrier instead of the home office.

Another reason I've come across is when there are multiple employees that are short term, but require access to locked doors/areas/time clocks/whatever. It isn't practical or cost effective to give lots of temp people badges, keys, or complex ID numbers easily faked or forgotten. So biometics allows for a signature that they bring with them. The application of this I ran into was an optical iris scanner, not fingerprint, but the concept can still be applied.
