BAR CODE KEYBOARD WEDGE READERS
A BAR CODE KEYBOARD WEDGE READER is attached to a computer through a port called
the keyboard interface. When a BAR CODE is scanned, the information is
transmitted as though it were keyed in the form of keyboard. Sometimes they’re
referred to as BAR CODE WEDGE READERS because they physically wedge between the
keyboard and the computer and attach as a second keyboard. One great advantage
of a BAR CODE KEYBOARD WEDGE READER is that BAR CODE reading can be added with
no software changes necessary; the software thinks that the data received was
entered by a speedy typist. With a BAR CODE KEYBOARD WEDGE READER, any program
that accepts keyed data will accept BAR CODE data with no change.
