Post by Sean Liming (MVP)William,
Because of the cost of the equipment, I have limited access to POS hardware.
Some vendors have been gracious enough to supply something for future book
updates and/or articles. The bar code scanners I have used are typical
retail scanners that use the sample SO from the POS for .NET SDK. I don't
have any recomendations on the type of scanner you are looking for.
I have seen a biometric scanner that MS has worked on. Sylvester La Blanc
just posted to the newsgroup that they will demonstrate a biometric reader
solution at NRF this month. He might be able to explain further.

Post by William StaceyThanks Sean! That is about the best info in one place I have seen so far.
1) Do you happen to have a recommendation for a card reader that reads
bar codes (i.e. employee badge)?
2) Has MS released an SO for their own Fingerprint reader (for the
Biometrics class)? If not, has any vendor? I am using the GrFinger sdk
at the moment, but it has a few minor issues in the .Net library (i.e.
always throws an exception in finialize method with some corrupt memory
error).
Not to boil the ocean here, but it seems this whole pattern would fit more
natural into the CCR pattern with a single port for each device and single
port for explorer notifications. After all, all these random inputs more
closely resemble robotics then anything else. Should be able to play with
Maestro soon for a high road solution for controlled concurrency in a
managed language (which also uses the CCR under the covers).

Post by William StaceyThis link is dead. I just want a list of devices that have SO and POS
support. I am finding nothing but case studies on the wpos site which
is frustrating.

Also, were are all the samples? I find almost nothing on the web and
have looked for an hour. The sdk contains almost no sample code. This
is very strange.
TIA

HandHeld has native .NET Service objects. Symbol has OPOS service
objects that can be used (you can use Symbol with the sample service
object included with the SDK in non-production environment with a few
tweaks. See the blog on how to do this - also see the Hands On lab on
the blog).
As for a list of service objects, because POS for .NET is part of a
standard that anybody is free to implement, there is no registry for
maintaing such a list.
As for the fingerprint reader, there is no SO for the Microsoft version.
Other vendors have been provided guidance for developing service
objects, but I don't know which ones have formally been published. I
demoed one at NRF. My best advice is to contact the vendor(s) of the
device you like in and ask if they have a .NET service objects. I wish
I could give you a more definitive answer, but as I said, there is no
registration of service objects.
