THE ARGUMENT
FOR AND AGAINST PEN-STYLE
BARCODE
READERS
Each of the several styles of
barcode
readers has a specific purpose as well as advantages and disadvantages.
Basically there are four different types of
barcode
readers and several styles of
barcode
readers that employ the use of one of the four technologies behind the
barcode readers. In this article we will review the least expensive of the
bunch, pen style
barcode
readers along with the strengths and weaknesses of this particular
model.
Pen-style
barcode readers are the simplest design and also the least costly of all
barcode
readers. Pen
barcode
readers use a source of light and a photo diode paired together in the
end of a wand or pen design. The diode in the
barcode
readers measures the amount of light reflected back from the barcode
label. Pen barcode readers contain no moving parts, need almost no
maintenance and thereby are known for their durability. These readers need
to be manually run along the barcode label in order to read the code.
Since the pen-style
barcode
readers need to touch the labels, after
time the labels can become smudged or damaged and eventually are rendered
completely useless and require replacement. Pen style
barcode
readers also prove the most difficult to use since human hands are the
ones directing the light source from the
barcode
readers. The pen-type
barcode
readers need to be held at just the right angle in order to effectively
pick up the light reflected back from the barcode labels.
Once you consider the advantages and disadvantages of the pen-style
barcode
readers, you'll probably decide that they are only worth purchasing if
keeping costs low is your main priority. |
