Assigning a permanent barcode to each site, location, item supplier and
customer creates an environment where a mobile device can be used to easily
keep track of inventory movements and alleviates the problem of data-entry
errors.
Barcodes get wider with the amount of numbers and characters you want
represented by them. A barcodes width is determined by the amount of numbers
or characters represented by the barcode. Some barcode scanners have a
limited width that they can read. If you have very long item numbers or location
numbers you may need to reconsider the numbering scheme or the scanner you
are using. Also be aware that many of the less expensive barcode readers do not
read barcodes that are bent, at an angle, too small or damaged. Consider the
possible disposition of your barcodes before choosing a scanner.
There are many different barcode formats or symbologies. The different
symbologies can be thought of as different fonts. The same characters are
represented by different symbologies in different ways, as shown below:
These different formats exist to provide ways to compress more data into a
smaller s pace, to represent a different set of characters or to enable scanning at
different angles or distances. In InventoryControl we use the symbology called
Code 128 for all the pre-built labels. All the scanners and mobile devices Wasp
supplies can read code 128. We suggest you use Code 128 because it supports
all numbers, upper and lower case characters and most special characters and it
reduces the most common barcodes.
Barcodes should be printed using a barcode printer or, if you have software
capable of creating a barcode, on a high quality laser or ink jet printer. You want
the barcode label to be high quality because low quality barcodes are harder to
scan and usually do not last long. InventoryControl is bundled with W asp
Labeler, which can print to a regular printer or a barcode printer. Remember to
