- Well, Pete, that's quite a lot of information you need and probably deserves a
- FAQ. For starters, see if you can get a copy of "The Barcode Book" by Roger
- Palmer (Helmers Publishing (603)924-9631 ). It will answer a lot of your
- questions. One good trade periodical is "ID Systems" - same number as above.
- There is another publication but, alas, I don't have a copy in front of me at
- the moment.
-
- There are literally hundreds of vendors of barcode equipment; several are good
- and some are not. Some relatively small firms are listed in the back of most
- microcomputer magazines.
-
- The hardware for the "keyboard" interface you mention is known as a "wedge"
- reader, a device connected in series between the keyboard and the CPU.
- Portable readers typically dump data through a serial port. RF portables
- (don't know of any IR portables) are usually multiplexed and operate directly,
- i.e. they don't dump data. However, the RF devices are at the high end of the
- price range.
-
- Hope this helps. E-mail me should you need more info.
