I've seen two different interpretations of "having a card reader at the 
door": 1) a scanner that tracks everyone as they enter or exit the door, 
and 2) a reader sitting at the door that you can swipe your badge on as 
you enter as an alternative to the blue sheets. I would find the former 
troublesome, but not the latter.

Another alternative to the card reader at the door is something I saw at 
one of yesterday's sessions: a card reader passed along with the blue 
sheets. (Would that be an eBlueSheet (tm)? :-) ) However, there was only 
one of those and the *other* blue sheet clip board did not have its own 
card reader.

A couple further thoughts:

*) With the blue sheets, we have parallelism as multiple sheets are 
passed around the room. Swiping a reader that's being passed around 
would be faster, so this might not be much of an issue. If this were 
chosen as the working model, it might be better to have two of the readers.

*) A number of people, such as WG chairs, come early to a meeting to set 
up. And at the end of a meeting, the WG chairs will often hold up the 
blue sheets to get any one to sign up that missed signing in earlier. A 
eBlueSheet needs to be able to handle both of these cases, and 
differentiate signins between meetings.
