You are right about the reader. It just reads the id of the tag and
passes it along to the computer.
Based on the info you've provided, you shouldn't have a problem using
the exisitng IOBluetooth.framework in Panther to do what you want.
However its impossible to say for 100% sure without information on the
Bluetooth RFID reader that you're going to use.  My guess is that its
just a serial device converted to work with Bluetooth.  In that case,
it likely just has a serial port service that uses an RFCOMM channel
for the communications.  If that's the case, it should be a simple
matter to write an application to select the device, open the RFCOMM
channel and communicate with it.
Nope. They are just RFID tags that the wand, a bluetooth device,
recognizes and can pass the id of to the computer/application. They
cost about $2.50 each but my inventory isn't very large ~1,000 items.
Don't you think that using BT modules for tags would make them VERY
expensive

 tags?

-------------- Original message --------------
...
Thanks for getting back to me Luc!
...

...
And thanks for the pointers. I've checked them out and there is
good
...
info there as well as in the examples. However, here is what I'm
...
looking to do.
...

...
Let's say I'm managing inventory in a warehouse and I have a 12"
...
PowerBook (Bluetooth-enabled), a hand-held wand
(Bluetooth-enabled) and
...
all around me are products that each have their own RFID
(Bluetooth)
...
tag on them.
...

...
In front of me is a crate of widgets, each widget with an RFID
tag. I
...
take the wand, which is associated with my PowerBook via
Bluetooth, and
...
I touch one of the products with the tag. Immediately on my
screen a
...
window opens with information about this product. Let's say this
...
products is a custom-built ! motorcycle and the window has info
about the
...
motorcycle. Maybe I add more info, noting that a custom seat was
added
...
to the motorcycle, I save and walk down the warehouse.
...

...
There is a pallet of new products now and each product has a tag. I
...
touch the wand to a product and up comes a window which allows me
to
...
add new data about this product. But instead of typing all this
data in
...
there is a board nearby which I can use to do data entry. On the
board
...
are various RFID tags, each one representing a value, or group of
...
values, back in the database. I touch a tag and information about
the
...
product is immediately entered. I touch another tag and a set of
...
information is entered.
...

...
Make sense?
...

...
I've seen this done before but want to know if I can do it with an
...
Apple and the Bluetooth SDK they have now or with Tiger.
...

...
Thanks for you! r time!

Hi,
...
...
...
...
I'm not sure of what you're asking exactly. For the examples of
...
...
Bluetooth for Apple, see on your Mac:
...
...
/Developer/Examples/Bluetooth/
...
...
...
...
For a guide, see:
...
...
http://developer.apple.com/documentation/DeviceDrivers/Conceptual/
...
...
Bluetooth/BT_Intro/chapter_1_section_1.html
...
...
...
...
For your app, I do not have enough info to really understand,
but I
...
...
would be happy to help you with more info.
...
...

Hi,
...
...
...
...
...
...
...
...
I'm be! ginning to get into Bluetooth technology and have some
...
...
...
...
application requirements which I'd like to run across this
list to
...
...
...
...
see if:
...
...
...
...
...
...
...
...
1. They are viable given the current Bluetooth SDK.
...
...
...
...
...
...
...
...
2. If not, will they be with the Tiger release?
...
...
...
...
...
...
...
...
3. Are there any Apple examples, or others for that matter,
which I
...
...
...
...
can use as a guide?
...
...
...
...
...
...
...
...
The app is a basic data entry and reporting tool to manage
inventory
...
...
...
...
of product. The idea is that each product has a Bluetooth tag
which
...
...
...
...
is read by a wand which then brings up either the product
...
...
...
...
information, if already in the database or a new entry screen
to put
...
...
...
...
the data into the database. The cool thing here is that the
computer
...
!  ; >>> will not be used by the person taking/managing inventor
y; they will
...
...
...
...
use the wand with a board that contains other Bluetooth tags
which
...
...
...
...
act as input ids for values in each of the entry screen's
fields.
...
...
...
...
...
...
...
...
Make sense? If not I can clarify further. T'would be nice to
know if
...
...
...
...
this is doable; seems like it.
...
...
...
...
...
...
...
...
Thanks!
