[thelist] Barcode Readers in ASP web apps?

Hey, Evolters.

I'm currently designing an ordering/tracking system for a company using ASP
and SQL Server, and they are REALLY REALLY wanting to use barcode scanners.
As in, scan a barcode and the webapp would redirect to a details page with
the ID# that was scanned in.

Has anyone else done this before?  With JUST ASP and DHTML?  From my
understanding, barcode readers emuluate keyboard strokes, so my initial
thought was to use DHTML, capture a special unused keyboard character like
the "~" key via the onKeypress method, trap the ID# and have the ASP page
process it accordingly.  What do you guys think?

ActiveX controls scare me, but I'm willing to learn it if it'll make my job
that much easier.

Any help would be MUCH appreciated, since I can't find any resources on
google.  Thanks!

(Incidentally, people at the company find the idea of typing in seven digit
ID numbers and pressing a submit button horrifying there.  Yet, they want
the application as web enabled.  Hrm...)
